Hi, I would like some clarification on what the bug in bash is that prevents us using [[ style tests when testing if a function exists. We have this in the two patches that change all the tests in makepkg: * if [ $(type ... preserved due to a bash bug with [[ and set -e and ERR traps I also have a patch from Cedric that makes the build() function optional which uses [[ for the "type -p" test. Here is an example script based on code Cedric provided: --start-- #!/bin/bash -e set -E trap 'echo >&2 "DANGER: ERRORS ABOUND!"' ERR build() { echo "build" } [[ $(! type -t build) = "function" ]] && echo "yes" || echo "no" [[ $(! type -t package) = "function" ]] && echo "yes" || echo "no" --end-- That outputs "yes" for the build function and "no" for the package function without an error trap being triggered. I know the "!" is a workaround to stop the error trap being triggered, but is there something wrong with that? Allan
