| | | | | ``rm'' -> ``rm -f'' so mv/rm may not ask for confirmation if you are not root

* Fix my own brokeness for the colon operator, when one of the argumentsjoerg1995-11-181-33/+31

* expr(1) didn't comply to Posix.2 and its own man page: anyjoerg1995-08-041-1/+13
| | | | | | | | comparisions have been made as string comparisions, even in cases where both operands clearly qualified as integers. The fix is to make the parser properly analyzing whether an operand is a valid integer or not.

* You will find enclosed some changes to make gcc -Wall more happy injoerg1995-03-191-2/+3
| | | | | | | | | /usr/src/bin. Note that some patches are still needed in that directory. I (Joerg) finished most of Philippe's cleanup. /bin/sh will still need *allot* of work, however. Submitted by: charnier@lirmm.fr (Philippe Charnier)

* Explicitly include <sys/types.h> before including <regex.h>. This isbde1994-09-051-0/+1
| | | | | apparently required by POSIX. It will be required in practice when the bogus inclusion of <sys/types.h> is removed from <stdio.h>.

* Fix grammar to eliminate support for unary minus expressions -- theyjtc1993-09-141-9/+8

* 1003.2 requires that lexical comparisons be done in locale specific manner,jtc1993-08-171-34/+29
| | | | | | | so we have to use strcoll() instead of strcmp(). 1003.2 requires that a null string be returned if a string does not match a \( \) subexpression. Replaced fprintf/exit with calls to err and errx as appropriate.
* Remove GNU regex.[ch] and use system's regex library. The library is stillconklin1993-08-021-2/+3
| | | | | GNU regex for now, but will be replaced as soon as an alternative is made availiable.
