Package: bash
Version: 3.1-1
Severity: wishlist
There exists the special variable $_, which contains the last arg of
the last command executed, amongst other things. It would be nice if
there were a special array that contained all args and program name of
last command to be executed (either in the foreground or background).
That way, I could use a trap that does the following:
set -e
trap "finalise" 0 HUP QUIT INT
function finalise() {
echo "failed on `hostname` at `date` -- last job to fail was
\"${LASTCMD[*]}\" with exit code $?"
...
trap - 0
exit 1
}
...
trap - 0
Thanks.
