Thanks, that did the trick!
Although I’m ordinarily loath to write GNU bash scripts, this
helps avoiding temporary files. This works:
-----cutting here may damage your screen surface-----
#!/bin/bash
export LC_ALL=C
subdir=x/y
while IFS=' ' read -r old new name; do
test x"$name" = x"refs/heads/master" || continue
if test x"0" != x"$(comm -23z \
<(git ls-tree -r -z "$old" "$subdir" | sort -z) \
<(git ls-tree -r -z "$new" "$subdir" | sort -z) | wc -c)"; then
echo >&2 'Untouchable files touched, commit rejected!'
exit 1
fi
done
exit 0
-----cutting here may damage your screen surface-----
Of course, set “subdir” in line 3 correctly, and GNU coreutils
are required for the NUL line termination, which is not an issue
here. (BSD has “-R ''” for sort(1), for example.)
