List git repositories with unpushed changes

Question

I'm reinstalling my OS. I have thousands of repos on my computer. I have a feeling that I've made a few changes in some repos while hacking around that are not committed and/or pushed.

From a bash shell on my Debian PC, what's the best way to find a list of changes that have not yet been committed/pushed to their remotes, and decide whether or not I want to keep the changes?

Answer 1

You may like the project multi-git-status from Ferry Boender.

https://github.com/fboender/multi-git-status.
"Show uncommited, untracked and unpushed changes in multiple Git repositories."

Answer 2

I'm assuming finding each repo and running git status in each repo is sufficient for your needs. In which case the following might be a starting point for you:

find / -name "*.git" -type d -print0 | xargs -0 -L 1 -i% bash -c "cd %/..; pwd; git status -s -uno"

find traverses your filesystem, starting at / (you may want to restrict that to perhaps ~), searching for .git diretories. The output (null-delimited to handle funny filenames) is piped to xargs, which cds to each repo, prints the pwd, and short-form git-status, without listing untracked files.

Answer 3

The previous answer finds uncommitted, but not unpushed commits.

This will find both:

find / -name "*.git" -type d -print0 | xargs -0 -L 1 -i% bash -c "cd %/..; pwd; git status -s -uno; git cherry -v 2>/dev/null"

git cherry shows the SHA1 of unpushed changes; -v adds the commit comment; and error redirection suppresses noisy output for repos that lack an upstream.
