I was running out of storage space on my machine, so I started to search for things to remove using Grand Perspective. Some of the big files were inside Git repositories, or rather, inside the .git directory of those repositories. I decided it was time to run the Git garbage collector on them, all of them.
I wrote this little script:
#!/usr/bin/env bash echo "Gitgcing $1" cd "$1"
and with this line:
find . -name ".git" -type d -exec gitgc "{}" ";"
run in my home directory, I got all my repos gc’ed.
