christos 92380da725 fixed previous booboo that broke command line editing input. 1995-10-06 21:38:18 +00:00
christos c1b02d9bff - Fix -v flag, so that it works properly when the shell reads from scripts.
- Bad style to fix my own PR, but I'd like to commit the parallel make
  changes soon, and this is a necessary prerequisite.

jtc d4fe82df8d Handle %q format directive; from Mike Long (PR #1454). 1995-09-14 16:19:06 +00:00
christos f9382bca1a Fix return builtin to work like it does in ksh:
When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.
What does joe posix have to say about this?
[fixes PR/1444]

christos 782cb68126 Fix bin/1240, from Dennis Ferguson. the exit builtin with no arguments
should return the exitcode of the previous command but it always returned 0.

pk edae5ead03 Relocate pointers after re-allocation of the job table. 1995-07-04 16:26:45 +00:00
jtc 88fc62fe16 Changed type of rlimit values from quad_t to rlim_t. Cast rlim_t's to

Eliminated unneccessary conditional.

mycroft 332b7d5213 Add a DPADD. 1995-06-10 20:19:40 +00:00
christos a45947b2a4 Changed so that 'PATH=newpath command' works, instead of looking at the
old path. Synced input.c with vangogh.

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...

christos 07bae7eddd Merge in my changes from vangogh, and fix the x=`false`; echo $? == 0
bug.

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.

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}:".
