* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-1/+1
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

| | | | | | use 'getcwd(NULL, 0)' just as pwd(1) does. Suggested by: bde
* Make sh(1) a little braver in the face of adversity. sh(1)steve1996-12-211-163/+16
| | | | | | | now handles the getpwd() init problem the same way as bash and ksh do. Also while I was in here, I cleaned up the format a little, removed some unnnecessary #if SYMLINKS cruft, and changed the pwd builtin to use getcwd(3) as Joerg suggested.

| | | | | | | | | | | | | | merge of parallel duplicate work by Steve Price and myself. :-] There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes. This closes a pile of /bin/sh PR's, but not all of them.. Submitted by: Steve Price <steve@bonsai.hiwaay.net>, peter
* A fix for the "cd -" coredump on a brand new /bin/sh. The problem waspeter1995-11-141-2/+5
| | | | | | noticed on a NetBSD bugs mailing list but this is entirely my own work. Inspired by: Scott Reynolds <scottr@plexus.com>, for NetBSD
* Obtained from: partly from 1.1.5bde1994-12-261-2/+4
| | | | | Convert "" to "." for "cd" and "cd ''". chdir("") is required to fail on POSIX systems.
* Get this braindead, mongoloid shell look in /stand for pwd if it can'tjkh1994-11-061-3/+8
| | | | | | | | | | find it in /bin. This is something of a kludge, I know, but consider my limited alternatives: I can't make this an execvp() without making people scream that I introduced a failure point or slowed down pwd, and I can't make it an optional macro since crunch doesn't let you pass arbitrary command-line args to the build of one of its crunch-ees. This is the simplest, if not the nicest looking, solution I could come up with.
