The content of the various files looks correct, and absence of "actual2" implies that one of the grep's failed, which is very odd considering that "out" has the expected content. Using the "out" file you attached, can you show the output of these commands? grep "^worktree.*/destination" out echo $? grep "^worktree.*/source" out echo $? I'd expect the first $? to report 0 and the second 1 in a working installation. Also, are you using an unusual 'grep'? What does "command -v grep" report?
