|
|
* History:
|
|
*
|
|
* 17/08/94 (Tim Norman)
|
|
* started.
|
|
*
|
|
* 08/08/95 (Matt Rains)
|
|
* i have cleaned up the source code. changes now bring this source into
|
|
* guidelines for recommended programming practice.
|
|
*
|
|
* cd()
|
|
* started.
|
|
*
|
|
* dir()
|
|
* i have added support for file attributes to the DIR() function. the
|
|
* routine adds "d" (directory) and "r" (read only) output. files with the
|
|
* system attribute have the filename converted to lowercase. files with
|
|
* the hidden attribute are not displayed.
|
|
*
|
|
* i have added support for directorys. now if the directory attribute is
|
|
* detected the file size if replaced with the string "<dir>".
|
|
*
|
|
* ver()
|
|
* started.
|
|
*
|
|
* md()
|
|
* started.
|
|
*
|
|
* rd()
|
|
* started.
|
|
*
|
|
* del()
|
|
* started.
|
|
*
|
|
* does not support wildcard selection.
|
|
*
|
|
* todo: add delete directory support.
|
|
* add recursive directory delete support.
|
|
*
|
|
* ren()
|
|
* started.
|
|
*
|
|
* does not support wildcard selection.
|
|
*
|
|
* todo: add rename directory support.
|
|
*
|
|
* a general structure has been used for the cd, rd and md commands. this
|
|
* will be better in the long run. it is too hard to maintain such diverse
|
|
* functions when you are involved in a group project like this.
|
|
*
|
|
* 12/14/95 (Tim Norman)
|
|
* fixed DIR so that it will stick \*.* if a directory is specified and
|
|
* that it will stick on .* if a file with no extension is specified or
|
|
* *.* if it ends in a \
|
|
*
|
|
* 1/6/96 (Tim Norman)
|
|
* added an isatty call to DIR so it won't prompt for keypresses unless
|
|
* stdin and stdout are the console.
|
|
*
|
|
* changed parameters to be mutually consistent to make calling the
|
|
* functions easier
|
|
*
|
|
* rem()
|
|
* started.
|
|
*
|
|
* doskey()
|
|
* started.
|
|
*
|
|
* 01/22/96 (Oliver Mueller)
|
|
* error messages are now handled by perror.
|
|
*
|
|
* 02/05/96 (Tim Norman)
|
|
* converted all functions to accept first/rest parameters
|
|
*
|
|
* 07/26/96 (Tim Norman)
|
|
* changed return values to int instead of void
|
|
*
|
|
* path() started.
|
|
*
|
|
* 12/23/96 (Aaron Kaufman)
|
|
* rewrote dir() to mimic MS-DOS's dir
|
|
*
|
|
* 01/28/97 (Tim Norman)
|
|
* cleaned up Aaron's DIR code
|
|
*
|
|
* 06/13/97 (Tim Norman)
|
|
* moved DIR code to dir.c
|
|
* re-implemented Aaron's DIR code
|
|
*
|
|
* 06/14/97 (Steffan Kaiser)
|
|
* ctrl-break handling
|
|
* bug fixes
|
|
*
|
|
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* added config.h include
|
|
*
|
|
* 03-Dec-1998 (Eric Kohl)
|
|
* Replaced DOS calls by Win32 calls.
|
|
*
|
|
* 08-Dec-1998 (Eric Kohl)
|
|
* Added help texts ("/?").
|
|
*
|
|
* 18-Dec-1998 (Eric Kohl)
|
|
* Added support for quoted arguments (cd "program files").
|
|
*
|
|
* 07-Jan-1999 (Eric Kohl)
|
|
* Clean up.
|
|
*
|
|
* 26-Jan-1999 (Eric Kohl)
|
|
* Replaced remaining CRT io functions by Win32 io functions.
|
|
* Unicode safe!
|
|
*
|
|
* 30-Jan-1999 (Eric Kohl)
|
|
* Added "cd -" feature. Changes to the previous directory.
|
|
*
|
|
* 15-Mar-1999 (Eric Kohl)
|
|
* Fixed bug in "cd -" feature. If the previous directory was a root
|
|
* directory, it was ignored.
|
|
*
|
|
* 23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
|
|
* Improved chdir/cd command.
|
|
*
|
|
* 02-Apr-2004 (Magnus Olsen <magnus@greatlord.com>)
|
|
* Remove all hard code string so they can be
|
|
* translate to other langues.
|
|
*
|
|
