Hallo Cygwains,
[Heck, I dunno... "Cygwinauts"?].
I have a possibly OT question, that is, a bash shell question. Lacking
the insight into the deepest reaches of shell-ology, I have come up
empty on all attempts to solve this one for myself. (Those attempts have
included doing `info bash' and reading the "Advanced Bash Scripting
Guide", an excellent resource available on the Web).
I am writing a shell script that chains together several commands in a
pipeline -- very *nix-ish. The first command in the pipeline is an
invocation of `make'. Here's the entire script code -- I've tried many
very elaborate or bizarre things, before this:
----------------------------------8<-----------------------------------
function powermake
{
declare -x LESS='-z-2$ -s~wR'
declare PAGER='/bin/less'
declare +x ECODE=
{ make "$@" || ECODE=$? ; } 2>&1 | tee $MAKE_ERR_TO | \
/cdv/f/scr/colormake.pl | $PAGER -O"${MAKE_ERR_TO}.colorlog"
if [[ $ECODE ]] # "0" and "1" are both TRUE; "null" is FALSE.
then $gvimexe --servername 'QUICKFIX' -q "$(cygpath -wla $MAKE_ERR_TO)"
else echo 'No "make" errors to diagnose: retval was ' '"'$ECODE'".'
fi
return $ECODE
}
----------------------------------8<-----------------------------------
The problem I am trying to solve is how to get the return value of the
`make' tool. If there was an error I need to know about it. But as it
stands, nothing that i have tried will cause me to see the VIM editor
session start up; the value in ECODE is apparently always "0".
Does anyone know how to do this -- how to pull out a return value from a
command in the middle of a pipeline?
Thanks,
Soren
