how can i return an exit value (to the invokers shell) of a command in a
list which gets piped into "more" ...
{ gcc 2>&1 see.c; xit=$?; if [ $xit ]; then exit $xit; fi; } | more
-------------------------------------------------------------------------
of course, "xit" ends up getting "wiped", and more is executed regardless.
i can't figure out how to do this without executing gcc 2x ...
such as follows ...
-------------------------------------------------------------------------
gcc 1>&- 2>&- see.c; xit=$?
if [ $xit != 0 ]; then blah; blah; exit $xit
else gcc 2>&1 see.c | more
fi
