Use case: You want to clean up your git history before pushing it and notice that one commit contains to many (unrelated) changes.
Installation: Put into a directory in you PATH, for example:
cp git-split.sh ~/bin/git-split
chmod +x ~/bin/git-split
Usage:
git split [-p] [--auto-stash] <commit>
-p Split patch wise instead of file wise
--auto-stash Stash and unstash changes in the current working tree
Example:
Split the commit abc1234 into multiple commits, so that each commit edits only one file:
$ git log --oneline --stat
3ec599e (HEAD -> main) weiter3
[...]
abc1234 file3~2: Huge commit
file1 | 2 +-
file2 | 2 +-
file3 | 2 +-
3 files changed, 3 insertions(+), 3 deletions(-)
