[ ]* seems overly, complex, no need for the brackets. I’d anchor to the
beginning of the line, and remove the g as there’s only one expected.
This should work:
argument=$(basename "$(sed -ne 's/^#! *//p;q')" $cmd)
However, if the first line is something like "#!/usr/bin/env python3", then
$argument will be "env python3" and somehow I assume that is not exactly
what the rest of the code expects.
The use case is that whatever is in shebang should be extracted and ran
verbatim, so truncating like your suggestion can work but has slightly
different semantic.
Might also be wise to assert that you found something here, so running
this on an ELF fails with an obvious error.
