In fact the following works just as well:

#v+ files=$(git diff-index --name-only --diff-filter=AM HEAD) perl -pi -e 's/\$\s*Id.*?\$/\$Id: git '$(TZ=UTC date +%s)' \$/g' $files git add $files #v-

But then again, it has two unpleasant side effects: (i) all modified files are added and (ii) if I abort a commit the file stays modified. (i) can be fixed by removing "git add" but then again (iii) even files which are not committed will be modified.
