This is interesting, but appart from maybe some CI/CD pipeline configurations I can't think of a particularly useful reason for it.. Anyone have some suggestions ?

  I've got ~ 70 git repos to move from AWS code commit to Gitlab and need to tweak config files in each one for the new hosting environment, so this should definitely help

  Im making small, similar changes across about 30 repos of "microservices", they're a pain the the ass to maintain as they all sit with different owners - I'm not about to make a change in each repo, git add, git commit, push etc.... 30 times over, this makes it easy. I actually found mu-repo today which is much better for this - see https://news.ycombinator.com/item?id=31906227 https://news.ycombinator.com/item?id=31906227

  Some of the most useful runs I've used it for is for refactoring of internal libraries. Something as simple as wanting to rename a function is theoretically very simple, but if this function is used in hundreds of other repositories, it will be very tedious. A script that upgrades the dependency + does a replace with sed or similar could be run to make this process way easier.

I have this simple script that I find immensely useful when dealing with multiple git repository present in the same folder: #!/usr/bin/env bash if [ $# -lt 1 ] then echo "$0: error: missing arguments" echo "usage: $0 <command> <args...>" exit 1 fi for folder in `find . -maxdepth 1 ! -path . -type d` do if [ -d "$folder"/.git ]; then pushd . > /dev/null cd "$folder" echo -e '\033[1;32m' echo `pwd` echo -e '\033[0m' "$@" popd > /dev/null fi done In a folder with multiple git repos, you will do something like this: $ gitall git status [...] $ gitall git remote update [...] $ gitall git rebase origin/master [...]

git itself has a command called for-each-repo[0], which you provide the name of a global config setting which contains a list of repository paths, and it will then run the specified command on each of those repositories. Example from the man page: git for-each-repo --config=maintenance.repo maintenance run [0]:https://gitirc.eu/git-for-each-repo.html https://gitirc.eu/git-for-each-repo.html
