Should we? After your patch, we "return" from inside a subshell. Is that portable? ISTR issues around that before, but it just have been when we are not in a function at all. Still, I wonder if: for ... do ( cd "$subtree" && generate_expected_cache_tree_rec "$dir$subtree" ) || return 1 done might be more obvious. > -generate_expected_cache_tree () { > - ( > - generate_expected_cache_tree_rec > - ) > -} I wondered what the "rec" was for, but I guess it is "recurse". Not a problem to keep it, but I wonder if it could be dropped in the name of shortness/simplicity (not worth a re-roll for sure, but maybe worth doing so if you re-roll for the above issues). -Peff
