cgd dcb82cbdbc needs string.h 1995-06-07 16:28:03 +00:00
christos 9d255ec409 Ignore result of sigaction when setting traps. Traps will succeed even 
on SIGKILL or SIGSTOP. This is what other bourne shells do. (suggested
by mycroft)
 1995-06-07 04:16:57 +00:00
christos b842cc2784 Avoid trapping SIGKILL. Pretend that we did, so that we will not keep 
failing trying to trap it later. This is what the other bourne shells do.
 1995-06-05 14:24:33 +00:00
christos 58e18fc330 Fixed bug where 
$ cat foo
echo $FOO

$ FOO=1 . ./foo
$ echo $FOO

Did not echo 1 at all. Now variable assignments before sourced scripts
are honored during and after the execution of the script.
 1995-05-28 18:09:48 +00:00
christos 4fb6f609aa Changed so that syntax errors (EXERROR) set the exit status to 2, 
and commands that are not found set the exit status to 1 like all
other bourne shells.
[It used to be 0 and 2 respectively]
 1995-05-19 15:08:55 +00:00
christos 56a08eccca Fixed bug where ${#} was interpreted incorrectly as ${#var} and thus 
misparsed. Keith Bostic reported it.
 1995-05-17 00:05:25 +00:00
cgd b5f33fc18e re-add an #endif that was (apprently) clobbered. 1995-05-15 03:29:54 +00:00
christos fbac2e9de2 Fixed new bug the previous fix introduced: 
false
    foo=bar
    echo $?

would print 1
Also fixed the long standing bug:

    false
    echo `echo $?`

would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient
 1995-05-15 02:47:38 +00:00
christos 2e1970487e Fixed bug caused by previous x=`false` not preserving the exit status fix. 
The if statement exit status broke...
 1995-05-14 04:19:18 +00:00
christos 07bae7eddd Merge in my changes from vangogh, and fix the x=`false`; echo $? == 0 
bug.
 1995-05-11 21:28:33 +00:00
christos dae6c6b963 Added missing resource limits and recognize "unlimited" as RLIM_INFINITY 1995-04-11 03:17:45 +00:00
christos df504509f1 1. Don't core dump on 'fc -l' (From Gerard J van der Grinten) 
2. PATH=xxx ls, does the PATH assignment first and then tries to find ls in xxx
3. VAR=xxx exec ls, does the variable assignment.
 1995-03-31 21:58:09 +00:00
christos 6ee2193d9a Reverted to set - turning off -x and -v. Charles corrected me... It is part 
of POSIX.
 1995-03-26 17:25:10 +00:00
christos ad1f891148 set - 
does not anymore clear the -x and -v flags. This was incompatible with
all other bourne shell implementations.
 1995-03-25 23:45:24 +00:00
mycroft 6bfd77e432 Fix typo in previous. 1995-03-23 00:01:03 +00:00

cgd 49f0ad8601 convert to new RCS id conventions. 1995-03-21 09:01:59 +00:00
christos 5c42185b5c Oops... typo in the IFS previous fix. 1995-02-28 23:27:24 +00:00
christos 6ab1954578 Changed so that backquote expansion eats all trailing newlines, not just 
the last one.
Reported by guido@gvr.win.tue.nl (Guido van Rooij).
Repeat By:

	echo "`cat file-with-many-newlines`"
 1995-02-28 23:09:43 +00:00
christos 3936aab031 Changed IFS string-splitting so that it breaks spaces even when IFS does not 
begin with a space, but contains one. Fixes PR bin/809.

        #!/bin/sh
        list="a  b c "
        echo "With ordinary IFS"
        for i in $list;do
            echo $i
        done
        IFS=":${IFS}"
        echo "With changed IFS"
        for i in $list;do
            echo $i
        done

Note that before the fix ":${IFS}" behaved differently than "${IFS}:".
 1995-02-28 22:46:12 +00:00
mycroft f5ad44b6ac Use S_IS*(). 1995-01-30 19:30:13 +00:00

${#WORD}
    ${WORD%PAT}
    ${WORD%%PAT}
    ${WORD#PAT}
    ${WORD##PAT}

jtc 6cd3ad1d11 ulimit builtin (PR #388) 
This public domain code, originally by Doug Gwyn, Doug Kingston, Eric

jtc 4aece6a461 Renamed builtins to builtins.def to eliminate make's (incorrect) circular 
dependancy between the builtins data file and builtins.c.

The bug only occured when there was no obj directory, and is a result of
NetBSD's better (compared to 4.4lite's) default make rules.

Fixes bug #301.

cgd f51f1b4c04 from Thomas Eberhardt <thomas@mathematik.uni-Bremen.de>: 
Some reordering and modifications in the Makefiles for sh, dump,
    restore to get dependicies right.  The README in /usr/share/mk
    states that it's a Bad Thing(tm) to add something after
    .include <bsd.prog.mk>, but this seems the only way to get the
    dependencies right.

jtc 67893cfee5 IEEE 1003.2 (D11.2.2.3) requires that the system's true and false be accessed
