Execute in repos

Run arbitrary commands in git repos or plain old directories simultaneously/concurrently.

-config
Repos are specified via -config [default="$HOME/Documents/repo.conf"]. It contains repo paths separate by newlines, wildcards are also allowed.
-config ... can be a command redirect (a filedescriptor) <(find -type d -name '*something*') or a regular file.

Any git command uses color by default, use -nocolor to disable color for git commands.

Hint: There is no order to how we output command output for repos, whichever go routine finishes first wins.

Examples

$ ~/Documents/golang/tools/execute-in-repos/execute-in-repos -config <(find ~/.tmux/plugins/  -maxdepth 1 -mindepth 1 -type d) -- ls
