2 * INTERNAL.C - command.com internal commands.
7 * 17/08/94 (Tim Norman)
10 * 08/08/95 (Matt Rains)
11 * i have cleaned up the source code. changes now bring this source into
12 * guidelines for recommended programming practice.
18 * i have added support for file attributes to the DIR() function. the
19 * routine adds "d" (directory) and "r" (read only) output. files with the
20 * system attribute have the filename converted to lowercase. files with
21 * the hidden attribute are not displayed.
23 * i have added support for directorys. now if the directory attribute is
24 * detected the file size if replaced with the string "<dir>".
38 * does not support wildcard selection.
40 * todo: add delete directory support.
41 * add recursive directory delete support.
46 * does not support wildcard selection.
48 * todo: add rename directory support.
50 * a general structure has been used for the cd, rd and md commands. this
51 * will be better in the long run. it is too hard to maintain such diverse
52 * functions when you are involved in a group project like this.
54 * 12/14/95 (Tim Norman)
55 * fixed DIR so that it will stick \*.* if a directory is specified and
56 * that it will stick on .* if a file with no extension is specified or
57 * *.* if it ends in a \
60 * added an isatty call to DIR so it won't prompt for keypresses unless
61 * stdin and stdout are the console.
63 * changed parameters to be mutually consistent to make calling the
72 * 01/22/96 (Oliver Mueller)
73 * error messages are now handled by perror.
75 * 02/05/96 (Tim Norman)
76 * converted all functions to accept first/rest parameters
78 * 07/26/96 (Tim Norman)
79 * changed return values to int instead of void
83 * 12/23/96 (Aaron Kaufman)
84 * rewrote dir() to mimic MS-DOS's dir
86 * 01/28/97 (Tim Norman)
87 * cleaned up Aaron's DIR code
89 * 06/13/97 (Tim Norman)
90 * moved DIR code to dir.c
91 * re-implemented Aaron's DIR code
93 * 06/14/97 (Steffan Kaiser)
97 * 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
98 * added config.h include
100 * 03-Dec-1998 (Eric Kohl)
101 * Replaced DOS calls by Win32 calls.
103 * 08-Dec-1998 (Eric Kohl)
104 * Added help texts ("/?").
106 * 18-Dec-1998 (Eric Kohl)

117 * Added "cd -" feature. Changes to the previous directory.
119 * 15-Mar-1999 (Eric Kohl)
120 * Fixed bug in "cd -" feature. If the previous directory was a root
