Restore console title after running a command
[reactos.git] / reactos / subsys / system / cmd / cmd.c
1 /*
2 * CMD.C - command-line interface.
3 *
4 *
5 * History:
6 *
7 * 17 Jun 1994 (Tim Norman)
8 * started.
9 *
10 * 08 Aug 1995 (Matt Rains)
11 * I have cleaned up the source code. changes now bring this source
12 * into guidelines for recommended programming practice.
13 *
14 * A added the the standard FreeDOS GNU licence test to the
15 * initialize() function.
16 *
17 * Started to replace puts() with printf(). this will help
18 * standardize output. please follow my lead.
19 *
20 * I have added some constants to help making changes easier.
21 *
22 * 15 Dec 1995 (Tim Norman)
23 * major rewrite of the code to make it more efficient and add
24 * redirection support (finally!)
25 *
26 * 06 Jan 1996 (Tim Norman)
27 * finished adding redirection support! Changed to use our own
28 * exec code (MUCH thanks to Svante Frey!!)
29 *
30 * 29 Jan 1996 (Tim Norman)
31 * added support for CHDIR, RMDIR, MKDIR, and ERASE, as per
32 * suggestion of Steffan Kaiser
33 *
34 * changed "file not found" error message to "bad command or
35 * filename" thanks to Dustin Norman for noticing that confusing
36 * message!
37 *
38 * changed the format to call internal commands (again) so that if
39 * they want to split their commands, they can do it themselves
40 * (none of the internal functions so far need that much power, anyway)
41 *
42 * 27 Aug 1996 (Tim Norman)
43 * added in support for Oliver Mueller's ALIAS command
44 *
45 * 14 Jun 1997 (Steffan Kaiser)
46 * added ctrl-break handling and error level
47 *
48 * 16 Jun 1998 (Rob Lake)
49 * Runs command.com if /P is specified in command line. Command.com
50 * also stays permanent. If /C is in the command line, starts the
51 * program next in the line.
52 *
53 * 21 Jun 1998 (Rob Lake)
54 * Fixed up /C so that arguments for the program
55 *
56 * 08-Jul-1998 (John P. Price)
57 * Now sets COMSPEC environment variable
58 * misc clean up and optimization
59 * added date and time commands
60 * changed to using spawnl instead of exec. exec does not copy the
61 * environment to the child process!
62 *
63 * 14 Jul 1998 (Hans B Pufal)
64 * Reorganised source to be more efficient and to more closely
65 * follow MS-DOS conventions. (eg %..% environment variable
66 * replacement works form command line as well as batch file.
67 *
68 * New organisation also properly support nested batch files.
69 *
70 * New command table structure is half way towards providing a
71 * system in which COMMAND will find out what internal commands
72 * are loaded
73 *
74 * 24 Jul 1998 (Hans B Pufal) [HBP_003]
75 * Fixed return value when called with /C option
76 *
77 * 27 Jul 1998 John P. Price
78 * added config.h include
79 *
80 * 28 Jul 1998 John P. Price
81 * added showcmds function to show commands and options available
82 *
83 * 07-Aug-1998 (John P Price <linux-guru@gcfl.net>)
84 * Fixed carrage return output to better match MSDOS with echo
85 * on or off. (marked with "JPP 19980708")
86 *
87 * 07-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
88 * First ReactOS release.
89 * Extended length of commandline buffers to 512.
90 *
91 * 13-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
92 * Added COMSPEC environment variable.
93 * Added "/t" support (color) on cmd command line.
94 *
95 * 07-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
96 * Added help text ("cmd /?").
97 *
98 * 25-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
99 * Unicode and redirection safe!
100 * Fixed redirections and piping.
101 * Piping is based on temporary files, but basic support
102 * for anonymous pipes already exists.
103 *
104 * 27-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
105 * Replaced spawnl() by CreateProcess().
106 *
107 * 22-Oct-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
108 * Added break handler.
109 *
110 * 15-Dec-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
111 * Fixed current directory
112 *
113 * 28-Dec-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
114 * Restore window title after program/batch execution
115 *
116 * 03-Feb-2001 (Eric Kohl <ekohl@rz-online.de>)
117 * Workaround because argc[0] is NULL under ReactOS
118 *
119 * 23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
120 * %envvar% replacement conflicted with for.
121 *
122 * 30-Apr-2004 (Filip Navara <xnavara@volny.cz>)
123 * Make MakeSureDirectoryPathExistsEx unicode safe.
124 *
125 * 28-Mai-2004 (Hartmut Birr)
126 * Removed MakeSureDirectoryPathExistsEx.
127 * Use the current directory if GetTempPath fails.
128 *
129 * 12-Jul-2004 (Jens Collin <jens.collin@lakhei.com>)
130 * Added ShellExecute call when all else fails to be able to "launch" any file.
131 *
132 * 02-Apr-2005 (Magnus Olsen <magnus@greatlord.com>)
133 * Remove all hardcode string to En.rc
134 *
135 * 06-May-2005 (Klemens Friedl <frik85@gmail.com>)
136 * Add 'help' command (list all commands plus description)
137 *
138 * 06-jul-2005 (Magnus Olsen <magnus@greatlord.com>)
139 * translate '%errorlevel%' to the internal value.
140 * Add proper memmory alloc ProcessInput, the error
141 * handling for memmory handling need to be improve
