Seems to be fixed in bash-3.0 Fixed in 3.1.1-alt1. ash still not fixed, but I don't care. |
$ cat test.sh : while getopts d: opt; do case "$opt" in d) dir="$(readlink -ev "${OPTARG:?}")" ;; *) exit 2 ;; esac done $ bash -e test.sh -d '' test.sh: line 1: OPTARG: parameter null or not set $ ash -e test.sh -d '' test.sh: 7: OPTARG: parameter not set or null $ Why does bash says it was line 1? I guess when bash enters subshell, internal line counter is reset to 1. And why does ash says it was line 7? It must have been line 4!
