Execute git command on all direct git subdirectories of the current directory using `git all`

git-all

git some * -- "$@"

git-some

#!/usr/bin/env bash

GIT_ALL_README.md

If you put the git-all command provided in this gist as an executable in your PATH then:

For a structure like:

/just/a/project/group/path

• project-1/
• project-2/
• project-3/

Where project-{1,2,3} are all git directories we can execute the following:

$ cd /just/a/project/group/path  
$ git all status -s  
./project-1  
?? some-new-folder/  
./project-2  
 M src/file.yml  
./project-3  

The empty output after project-3 is obviously no status change reported by git status -s.
Of course all commands work even though some of them may not be appropriate for bulk execution. But you can simultaneously checkout branches, pull, log --oneline and more.

git-some behave the same except it takes specific project to apply the commands to. Example:

$ cd /just/a/project/group/path  
$ git some project-1 project-2 -- status -s  
./project-1  
?? some-new-folder/  
./project-2  
 M src/file.yml
