90 1 Getting started
91
92 1.1 What is Midnight Commander?
93
94 The Midnight Commander is a user-friendly yet powerful file manager
95 and visual shell, useful to novice and guru alike. It provides a
96 clear, user-friendly, and somewhat protected interface to a Unix
97 system while making many frequent file operations more efficient and
98 preserving the full power of the command prompt. You will wonder how
99 you could ever live without it.
100
101 For more thorough description take a look at the announcement of
102 Midnight Commander 4.0.
103
104 1.2 [UPDATED] Does it run on my machine?
105
106 Yes, Midnight Commander can run on almost any machine, including Unix
107 clones, Windows 95/NT and OS/2. Midnight Commander does not run on
108 Macintosh.
109
110 Midnight Commander uses GNU autoconfigure which can automatically
111 configure Midnight Commander for use on almost any (if not every) Unix
112 clone. Following configurations have been tested:
113 * i386-*-linux1.x, 2.x
114 * alpha-linux-linux2
115 * sparc-linux-linux2.x
116 * sparc64-linux-linux2.1
117 * mips-sgi-irix5.x, 6.x
118 * mips-dec-ultrix4.3
119 * rs6000-ibm-aix3.2.5
120 * sparc-sun-sunos4.1
121 * sparc-sun-solaris2.3, 2.4, 2.5
122 * sparc-sun-netbsd1.0
123 * hppa-hp-hpux9
124 * hppa-hp-hpux7
125 * m68k-apple-aux
126 * unixware
127 * mc88110-aviion-dgux5.4R2.01
128 * i386-*-sco3.2v4.2
129 * i386-*-sco3.2v5
130 * i386-*-windows-nt-3.51, 4.0
131 * i386-*-windows95
132 * i386-*-os2
133
134 See http://mc.blackdown.org/mc/download.html.
135
136 There is also a preliminary Ms-Dos port at
137 http://mc.blackdown.org/cgi-mc/download/DOS/.html (but no Ms-Dos
138 binary).
139
140 Windows 95/NT port is compiled with Microsoft Visual C++ but it might
141 be possible to use cygwin32 or djgpp instead.
142
143 1.3 Does it work with my terminal?
144
145 Yes, it does.
146
147 Because Midnight Commander is a full screen program it doesn't run on
148 dummy terminals but anything more advanced will do (like vt100). If
149 your terminal works with vi, emacs, elm or pine it will work with
150 Midnight Commander.
151
152 The XView and Tk editions currently under development will require an
153 X terminal.
154
155 1.4 What else do I need to run MC?
156
157 You need an Unix compatible operating system or Windows 95/NT or OS/2.
158
159 If you want to use mouse on the Linux console you need General Purpose
160 Mouse server from iride.unipv.it: /pub/gpm/. You need nothing extra to
161 use mouse on xterm.
162
163 To compile the XView edition (currently under development) you need
164 XView library. Xpm library and X11 non-rectangular shape extensions
165 are recommended.
166
167 To compile the Tk edition (currently under development) you need
168 Tk-4.0 libraries. Compilation of the Tk version won't be easy. Contact
169 Miguel for details.
170
171 If you do not want to use the slang library you could try using
172 ncurses (we recommend only version 4.1 and above).
173
174 You can get it along with other curses libraries, too, but results may
175 not be pretty or even usable.
176
177 1.5 Is Midnight Commander PD? Copyrighted?
178
179 Midnight Commander is under GNU Public License which basically means
180 that you may freely copy, change and distribute it, but that you may
181 not impose any restrictions on further distribution, and that you must
182 make the source code available. This is not the same as Public Domain.
183 For details, the GNU license is included in the Midnight Commander
184 source distribution (the COPYING file).
185
186 Midnight Commander is nowadays officially a part of GNU project. All
187 the authors of the Midnight Commander have given all their rights on
188 the program to the Free Software Foundation.
189
190 1.6 Where can I get Midnight Commander?
191
192 See http://mc.blackdown.org/mc/download.html. There are about seventy
193 download sites. Note that the newest files might not be present on all
194 the download sites yet.
195
196 In short: the main site is ftp://ftp.nuclecu.unam.mx/linux/local/ and
197 the sunsite.unc.edu mirrors have MC in the
198 /pub/Linux/utils/file/managers/mc directory.
199
200 1.7 I don't have FTP access. Where can I get MC?
201
202 Most Linux CD-ROMs include Midnight Commander. For example, Slackware,
203 Yggdrasil, S.U.S.E., Jurix, RedHat, Caldera and Debian.
204
205 2 Keyboard
206
207 2.1 What does documentation mean with the C-?, M-? and F? keys?
208
209 Midnight Commander documentation uses emacs style names for keyboard
210 keys.
211
212 C stands for the Ctrl key. For example, C-f means that you should hold
213 down the Ctrl key and press the f key.
214
215 M stands for the Meta key. Your terminal might call it Alt or Compose
216 instead of Meta. For example, M-f means that you should hold down the
217 Meta/Alt/Compose key and press the f key. If your terminal doesn't
218 have Meta, Alt or Compose or they don't work you can use Esc. For M-f
219 press the Esc key and then press the f key.
220
221 F? stands for a function key. If your terminal doesn't have function
222 keys or they don't work you can use Esc. For example, for F3 press the
223 Esc key and then press the 3 key.
224
225 2.2 [UPDATED] Why don't function keys (or some other key) work?
226
227 Your terminfo or termcap database has missing or incorrect definations
228 for function keys. Type "mc -V" to see what terminal database is being
229 used. If the result is "using the S-Lang library with terminfo
230 database" you should install one of the enhanced terminfo databases
231 included in the Midnight Commander source distribution. For example,
232 if you are using xterm type "tic xterm.ti".
233
234 If the result is "using the S-Lang library with termcap database" you
235 should fix your /etc/termcap database.
236
237 Best terminfo database is bundled with ncurses 4.2
238
239 You can select whether Midnight Commander will use terminfo or termcap
240 database by giving --with-terminfo or --with-termcap option to the
241 configure. Default is terminfo if found, otherwise termcap.
242
243 If you don't have permissions to edit terminal databases you can use
244 Learn keys feature of Midnight Commander instead. Press Esc 9 o k and
245 follow instructions.
246
247 If all else fails you can emulate function keys by first pressing the
248 ESC key and then one of the number keys. For example, if you want to
249 produce F9, press ESC, then 9. If you don't have a ESC key on your
250 keyboard you can try alt-9 or meta-9.
251
252 2.3 How do I use function keys F11 to F20?
253
254 These can mapped to function keys F1 to F10 with Shift held. eg.
255 function key F13 can be activated by pressing Shift-F3. You can define
256 the keys this way in the Options menu. The convention for PC keyboards
257 is that F11-20 always means Shift with F1-10
258
259 Note! Windows 95/NT and OS/2 ports use F11 and F12 keys to change the
260 current disk drive. In this case F11 and F12 mean the real F11 and F12
261 keys, not shift-F1 and shift-F2.
262
263 2.4 Why does the ESC key behave funny?
264
265 Midnight Commander uses the ESC key as a prefix for simulating the
266 Meta and Alt keys (for terminals which don't have Meta or Alt, see the
267 three previous questions). For example, pressing ESC-a is the same as
268 pressing Meta-a. In addition most terminals use ESC for internal
269 representation of arrow keys, function keys and other enhanced keys.
270 If you want to use ESC to cancel things you have to press it twice i.
271 e. ESC-ESC. If you find this cumbersome you can generally use F10 to
272 cancel. Alternatively turn on the old_esc_mode setting in the
273 ~/.mc.ini file. The old_esc_mode setting makes ESC work as a prefix
274 only if another key is pressed within 0.5 seconds. After 0.5 seconds
275 the ESC key cancels. There is no way to make ESC cancel immediately
276 (if we want to be able to use arrows keys and function keys).
277
278 X terminals allow more control over keyboard, so these ESC limitations
279 might not concern the forthcoming XView and Tk editions of the
280 Midnight Commander.
281
282 2.5 How can I add the plus sign (+) on the command line?
283
284 Press C-q first, then press the + sign.
285
286 The plus key is the hotkey for the select files command. If you want
287 to add a literal plus on to the command line you must quote it by
288 pressing C-q first.
289
290 Another common key which needs the C-q prefix is backslash "\".
291
292 3 Mouse
293
294 3.1 How do I enable mouse support?
295
296 Invoke mc like this (without quotes): "mc -x". If this doesn't work
297 upgrade to a terminal which compatible with the Xterm mouse sequences.
298
299 Alternatively, on Linux console you can use GPM.
300
301 3.2 How do I cut and paste text with mouse?
302
303 Hold down shift key while using mouse to cut'n'paste.
304
305 4 Display
306
307 4.1 Why do I keep getting "Terminal not powerful enough for SLang"?
308
309 This means that your terminfo databases do not contain the correct
310 definitions for your terminal.
311
312 You could try using a different terminal setting. If you use csh or
313 tcsh:
314
315 setenv TERM vt100
316
317 or if you use sh, bash, ksh or zsh:
318
319 export TERM=vt100
320
321 If this doesn't help you can recompile MC to use termcap instead of
322 terminfo:
323
324 ./configure --with-termcap
325 make
326
327 4.2 [UPDATED] Why don't line drawing characters work?
328
329 Since version 4.0.13 there's the commandline option -a to force use of
330 +, |, - for line drawing (only available when compiled with SLang).
331 Use this -a option if any of the suggestions below doesn't help.
332
333 In general, there are three subcases:
334 * Lines are shown as ASCII characters like this
335
336 +---------+
337 | |
338 +---------+
339 This also happens when you use the -a option. Other than that possible
340 reason is 1, 2 or 3 (see below).
341 * Lines are shown as lower case characters like this
342
343 lqqqqqqqqqk
344 x x
345 mqqqqqqqqqj
346 Possible reason is 2 or 3 (see below).
347 * Lines are shown as blanks or missing characters. Possible reason
348 is 3 or 4 (see below).
349
350 The reason for the problem is one of following:
351 1. Your curses library might not support line drawing characters.
352 Slang, Ncurses and System V curses do support them, BSD curses
353 doesn't. MC uses Slang by default so this is not usually a
354 problem.
355 2. Your terminal might not support line drawing characters. Vt100
356 compatible terminals, rxvt, xterm and color_xterm do support them.
357 3. Your terminfo or termcap database might have missing or incorrect
358 definations for line drawing characters. Set the acsc variable in
359 the terminfo database like this:
360 acsc=a\376k\277l\332m\300j\331n\305w\302v\301u\264t\303q\304x\263h
361 \2600\333
362 Don't forget issue 'tic' command. This supposes you are using pc
363 character set. The octal values might be different for other
364 character sets. If you are using termcap instead of terminfo, you
365 should modify above solution appropriately.
366 4. Your terminal font might not support line drawing characters. Try
367 changing the font.
368
369 Here is Miguel's answer to Torben on this subject.
370
371 Torben:
372
373 When I load consolefonts/iso01.f16, I get perfectly right national
374 characters, but the line drawing characters in mc get wrong. Is it
375 a mc problem, or is it a problem with the font? (I guess it is).
376
377 Is there a trick?
378
379 Miguel:
380
381 First of all, we should determine whether the font has line drawing
382 characters or not.
383
384 If it has line drawing characters, then a new terminfo entry should
385 be written for this specific case. Let's call this linux-iso01. The
386 acsc variable should be modified to reflect which characters are
387 used to do the line drawing.
388
389 If it does not have line drawing characters, then we should get rid
390 of the switch to acsc sequences and make the acsc sequence be just
391 a mapping to the ugly +, -, |, - characters.
392
393 You can get your terminfo definition by running the infocmp
394 program, making the proper changes and running the tic program to
395 compile your new terminfo database.
396
397 4.3 Can one use latin-1 characters without losing the lines?
398
399 Yes, you need a correct font and a correct termcap/terminfo database.
400
401 For font, if you use xterm try "xterm -fn fixed".
402
403 For termcap/terminfo database, change the acsc capability in the
404 database.
405
406 4.4 I have problems with entering/viewing national characters!
407
408 Upgrade to version 4.0.12 or newer.
409
410 From the Options - Display Bits dialog select Full 8 bits or ISO
411 8859-1. In addition, select 8 bit input from the same dialog.
412
413 4.5 How can I get colors?
414
415 Invoke mc like this (without quotes): "mc -c".
416
417 If you get colors, be happy.
418
419 If your terminal stays black and white, your terminal doesn't support
420 color. You might want to upgrade to a terminal which compatible with
421 the ANSI color sequences.
422
423 If your terminal goes compelety black, see the next question.
424
425 More detailed answer:
426
427 First, check that your terminal supports color. Color_xterm, rxvt and
428 Linux console do support, most other terminals don't. You can test
429 color support with following simple C program:
430
431 #include <stdio.h>
432
433 int main (void){
434 printf ("\033[32m Hello world! \033[m\n");
435 return 0;
436 }
437
438 Compile and run it. If you see "Hello world!" text in green your
439 terminal supports color, otherwise not (however, for color_xterm see
440 also the next question).
441
442 Second, check that you are using Ncurses or the Slang library (type
443 "mc -V" to find out), in addition some System V curses implementations
444 do support color, most don't.
445
446 With Slang library you can force color support by setting the
447 environment variable COLORTERM to any value.
448
449 Third, if you use ncurses library, check that your terminfo database
450 supports color. If not you should install one of the enhanced terminfo
451 databases included in the Midnight Commander source distribution.
452
453 Fourth, you might want to set the TERM environment variable so that
454 you use the correct terminfo database or termcap entry.
455
456 If you use color_xterm (or rxvt) the correct value might be
457 xterm-color, xtermc or simply xterm.
458
459 If you use Linux console the correct value for TERM is linux or
460 console.
461
462 4.6 My color_xterm goes completely (or partially) black!
463
464 Some color_xterm terminals define all colors as black instead of the
465 standard ANSI colors. This makes them go completely black when you try
466 to use Midnight Commander with colors.
467
468 You will have to override the defaults. Create a file "color.defaults"
469 which has the following contents:
470
471 color_xterm*color0: Black
472 color_xterm*color1: Red
473 color_xterm*color2: Green
474 color_xterm*color3: Yellow
475 color_xterm*color4: Blue
476 color_xterm*color5: Magenta
477 color_xterm*color6: Cyan
478 color_xterm*color7: White
479 color_xterm*background: White
480 color_xterm*foreground: Black
481
482 (replace color_xterm with the name of your color_xterm, color_xterm
483 mentions its name in its title bar)
484
485 Now type:
486
487 xrdb -merge color.defaults
488
489 Alternatively you can add the suggested contents of the color.defaults
490 file to your .Xdefaults or .Xresources file (or what ever the name of
491 your X configuration file is). Or you can replace your non-ANSI
492 color_xterm with an ANSI color_xterm.
493
494 4.7 Where can I get color_xterm?
495
496 Try ftp.x.org: /contrib/utilities/colour_xterm.tar.gz.
497
498 Alternatively, rxvt is a better choice, see
499 http://mc.blackdown.org/cgi-mc/download/rxvt/.html
500
501 4.8 I got colors working with MC but the other programs don't work at all
502 anymore!
503
504 Midnight Commander uses terminfo database (if available) but many
505 other programs use termcap database. If you set the TERM environment
506 variable to a value which has no corresponding entry in termcap
507 database those programs stop working. You should add the new value of
508 TERM to the termcap database.
509
510 Example: If you have set TERM to xterm-color locate from /etc/termcap
511 the line which starts:
512
513 xterm|vs100|xterm terminal emulator
514
515 Change it to start:
516
517 xterm|xterm-color|vs100|xterm terminal emulator
518
519 4.9 Why are there both terminfo and termcap? Wouldn't one database be enough?
520
521 You might want to read the Unix-haters handbook at
522 http://www.digital.de/people/jmh/Unix_Haters/unix-haters.html. It
523 lists many more reasons why Unix sucks.
524
525 You can configure which terminal database you want to use with the
526 "--with-termcap" and "--with-terminfo" flags of configure. If you
527 don't specify them, the configure script will try to use terminfo if
528 available otherwise it will use termcap.
529
530 5 Graphical user interface
531
532 5.1 Xview and Tk editions?
533
534 Get the newest development version, give the "--with-xview" or
535 "--with-tk" option to the configure and otherwise compile as usual.
536 See Download.
537
538 Xview and Tk editions are work in progress, they are not as robust as
539 the text mode edition.
540
541 6 Command line problems
542
543 6.1 How do I stay in the last directory when I exit Midnight Commander?
544
545 See the description of the -P option in the Options section of the
546 manual.
547
548 6.2 How can I access command line history?
549
550 You can browse previous commands with M-p and M-n. Alternatively, you
551 can summon the command history listbox by pressing F9 c h.
552
553 6.3 How can I complete commands, file names, variable names and so on?
554
555 Just press M-Tab. Press M-Tab again to get a listbox if there are
556 multiple possible completions.
557
558 6.4 [NEW] I am using ksh. Can I use functions defined in the .kshrc within
559 MC?
560
561 Sorry, MC only supports bash, tcsh and zsh functions. Ksh functions
562 are not supported because ksh lacks the necessary hooks needed for
563 subshell integration.
564
565 Switch to bash or zsh. They are both quite compatible with ksh. Your
566 ksh functions should work as such or after minimal changes.
567
568 6.5 [NEW] Is there any way to include additional options or hot keys to MC?
569
570 Yes, F2 invokes an user menu which fully configurable. You can add any
571 shell commands to the user menu. See
572 http://mc.blackdown.org/mc/manual-d.html#8 for more info.
573
574 Another way to add functionality is the external panelize feature. See
575 http://mc.blackdown.org/mc/manual-d.html#4 for more info.
576
577 And finally, you can code any feature you want yourself. MC source
578 code is free which means you can change it anyway you want. There are
579 some limitations to make sure MC stays free. See GNU General Public
580 License for details.
581
582 7 Virtual file systems
583
584 Note! Virtual file systems are supported by Unix ports only. The
585 Windows 95/NT and OS/2 ports do NOT support virtual file systems. This
586 means you haven't got ftp, zip or tar support on Windows 95/NT and
587 OS/2.
588
589 7.1 How can I see the contents of a tar archive?
590
591 If you use keyboard just move the selection bar on the tar file and
592 press enter.
593
594 If you use mouse just doubleclick on the tar file.
595
596 If these procedures don't work, your .mc.ext file is faulty. Replace
597 it with one from the MC source distribution.
598
599 You can also enter a tar archive by typing "cd tar:filename.tar.gz"
600 where filename.tar.gz is the name of the archive.
601
602 The recognized suffixes for tar archives are .tar, .tar.gz and .tgz.
603 If your tar archive uses different suffix you have to rename it.
604
605 7.2 How do I get out of a tar archive?
606
607 Just press enter on the toplevel ".." file or chdir to a non-tar
608 directory. Just typing "cd" with no parameters is enough (it will take
609 you to your home directory).
610
611 7.3 How do I do anonymous ftp with MC?
612
613 Just type "cd ftp://hostname" where hostname is the name of the host
614 you want to connect. Alternatively, select FTP link from the Left or
615 Right menu and type the name of the host you want to connect.
616
617 7.4 How do I do non-anonymous ftp with MC?
618
619 Non-anonymous ftp works just like the anonymous ftp but you give the
620 login name with the host name. For example, type "cd
621 ftp://username@hostname".
622
623 7.5 How do I close an ftp connection?
624
625 Just chdir to a non-ftp directory. Just typing "cd" with no parameters
626 is enough (it will take you to your home directory).
627
628 Internally Midnight Commander closes ftp connection only after a
629 timeout. This isn't visible to the end user.
630
631 7.6 Why aren't the contents of ftp panel updated?
632
633 Update is skipped because there would be a serious performance
634 penalty. Constantly updating directory panels through a ftp connection
635 would take too much time.
636
637 You can use C-r to force an update.
638
639 7.7 [NEW] What kind of proxy server works with Midnight Commander?
640
641 Midnight Commander only supports ftp-like ftp proxies. Common WWW
642 proxies (like Squid) are not supported yet because they make ftp
643 connections look like http connections.
644
645 8 Other common problems
646
647 8.1 [UPDATED] How do I get the internal editor to work?
648
649 The F4 key defaults to an external editor because thats what most
650 people are used to. To use the internal editor, select Configuration
651 from the Options menu and check the 'use internal edit' option.
652
653 Alternatively add the line
654 use_internal_edit=1
655
656 under the [Midnight-Commander] section in your .mc.ini file (which is
657 in your home directory).
658
659 To make the editor work all the time, go to the default/* section in
660 the file lib/mc/mc.ext file and remove the line
661
662 Edit=%var{EDITOR:vi} %f
663
664 The internal editor will now be invoked for anything not specified
665 elsewhere in the mc.ext file.
666
667 Make sure that you edit the correct mc.ext file. The Midnight
668 Commander first checks the existance of $HOME/.mc.ext. If this file is
669 missing MC will use $prefix/lib/mc/mc.ext instead ($prefix can be
670 changed with configure before compilation and it defaults to
671 /usr/local).
672
673 When you run `F9/Command/Extension file edit' for the very first time
674 Midnight Commander copies the system-wide mc.ext from $prefix/lib/mc
675 into your home directory because you need write access in order to
676 change it.
677
678 And please don't forget that "make install" overwrites
679 $prefix/lib/mc/mc.ext.
680
681 8.2 Why doesn't "mcedit newfile" work?
682
683 This is a known bug.
684
685 If the newfile doesn't exist, mcedit fails.
686
687 Start mcedit with no parameters, this will create a blank file. Then
688 save the file with whatever name you like.
689
690 8.3 [UPDATED] Is there any way to 'bookmark' favourite ftp-fs links?
691
692 Use the directory hotlist. Just press control-backslash. If your
693 national keyboard layout doesn't have backslash key, just press the
694 control key with the key which is the backslash key in the English
695 keyboard layout.
696
697 8.4 When copying the directories lose their original date, uid and gid!
698
699 This is a known bug. At moment only files preserve their original
700 settings when copying, not directories.
701
702 Uid and gid is fixed since 4.0.1. "Preserve UIDs/GIDs" in the copy
703 dialog needs to be checked and you must be root.
704
705 Date problem is supposed to be fixed with 4.0.13.
706
707 8.5 [UPDATED] Why I keep getting: "There is no disk in the drive. Please
708 insert a disk into drive D:"?
709
710 This is a known bug of the Windows 95/NT and OS/2 ports. MC looks its
711 configuration files from the D:\MC directory and if the D: drive is a
712 removable drive (like a CD ROM drive) and there is no disk in drive
713 you get this message everytime you try to do anything.
714
715 Since version 4.0.6 you can specify the actual location of the
716 Midnight Commander configuration files with the MCHOME environment
717 variable.
718
719 8.6 [NEW] When I start Midnight Commander, nothing happens!
720
721 First, invoke MC without subshell support: "mc -u". If this helps
722 check the shell you are using. Subshell support works best with bash
723 although tcsh and zsh are also supported. You might want to upgrade
724 your shell to a newer version. If you use something else than bash,
725 tcsh or zsh, subshell support is disabled automatically.
726
727 If disabling subshell doesn't help, try to reconfigure MC with
728 "--with-our-slang" and "--with-termcap" options and recompile. If this
729 helps, there is something wrong with your terminfo database or shared
730 slang library. For better terminfo databases see chapter 4. For a
731 better slang library, upgrade to a newer version or keep using the
732 "--with-our-slang" option.
733
734 8.7 [NEW] When I try to view a file MC hangs!
735
736 This is known bug. A quick fix is "chmod 666 /dev/tty". For a more
737 complete fix, see http://mc.blackdown.org/mc/maillist/97-10/98.html.
738
739 This bug will probably be fixed in 4.1.6.

790 9.2 Do I dare to use a development version?
791
792 I am afraid you have to answer to this question yourself. Development
793 versions seldom cause data loss but they have usually got many bugs.
794 It's up to you to judge whether new features outweight the bugs.
795
796 9.3 How can I report a bug/request for a feature?
797
798 You might first want to get the newest development version to see if
799 the bug is fixed or the feature is added already.
800
801 Send your report/request to mc-devel@roxanne.nuclecu.unam.mx or
802 mc@roxanne.nuclecu.unam.mx. These mailing lists are the most certain
803 way to contact the developers. Remember to mention if you are not on
804 the mailing list to make sure that you will receive a copy of replies.
805
806 Give as much details as possible. A too long message is a lot better
807 than a too short message.
808
809 For segmentation faults a stack backtrace is appreciated. You can
810 produce stack backtrace as follows:
811 * If segmentation fault produced a core file:
812 1. Load the core file by typing "gdb mc core" or "dbx mc core".
813 2. Type "where".
814 3. Cut and paste the results to your message.
815 * If segmentation fault didn't produce a core file:
816 1. Load mc by typing "gdb mc" or "dbx mc".
817 2. Start mc by typing "run".
818 3. Try to reproduce the segmentation fault by doing whatever you
819 did last time when the segmentation fault occurred.
820 4. Type "where".
821 5. Cut and paste the results to your message.
822 6. For the future you might want to check out what is the
823 command in your shell to allow producing of the core files.
824 Usually it is "limit coredumpsize unlimited" or "ulimit
825 coredumpsize" or "ulimit -c unlimited".
826
827 9.4 How can I join the development?
828
829 To join the development just code the feature you want to add and send
830 your patch for inclusion. Email address is mc-devel@nuclecu.unam.mx.
831 Before you start coding check the latest development version. It might
832 be that your feature has already been implemented.
833
834 Note that the authors of the Midnight Commander have given all their
835 rights on the program to the Free Software Foundation. You will have
836 to do the same if you contribute non-trivial patches. Otherwise we
837 have to reject your patches in order to avoid copyright problems.
