It is a small for loop, which I needed for a git cleanup.

##### Git clean I have all my git repositories in my ~/git folder. Sometimes those things grow big and I run a `git gc` on them. Now I had not done that for a few weeks and my git folder was getting huge. Git has a nice command, git gc, which clean up stuff. I don't know how exactly, but I do know it works. This command will find all directories, 1 level deep. Then it will go into them (pushd), issue the command (git gc) and go back to the above directory (popd). remy@solaris3 $~/git: for D in `find . -maxdepth 1 -type d`; do pushd $D; echo "==> DIR ${D}, COMMAND: git gc"; git gc; popd; done ##### Other stuff You can also use it for other things, like copy a license file to all your software source code directories remy@solaris3 $~/git: for D in `find . -maxdepth 1 -type d`; do pushd $D; echo "==> DIR ${D}, COMMAND: cp ~/LICENSE ./"; cp ~/LICENSE ./; popd; done You might want to zip all directories? Check if a file exists? What more to think about? [1]: https://www.digitalocean.com/?refcode=7435ae6b8212 --- License: All the text on this website is free as in freedom unless stated otherwise.
