Typically git rev-parse --show-toplevel prints the folder containing the .git folder regardless what subdirectory one is in. One exception I have found is that if one is within the context of git rebase --exec then show-toplevel always just prints the current directory it's running from.
Repro (starting with cwd within git project): > (cd xdiff; git rev-parse --show-toplevel) ... path to git repository > git rebase -i 18404434bf406f6a6f892ed73320c5cf9cc187dd # Stop at some commit for editing > (cd xdiff; git rev-parse --show-toplevel) ... path to git repository > git rebase 18404434bf406f6a6f892ed73320c5cf9cc187dd -x "(cd xdiff; git > rev-parse --show-toplevel)" ... path to git repository/xdiff !!! This seems like incorrect behaviour to me since it's a weird inconsistency (even with other rebase contexts) & the documentation says "Show the absolute path of the top-level directory." with no caveats. Thanks, Vital
