Problem

I build an app and use git branches.

Branches sum up, I don’t know which branches are already merged into master and I lose overview.

git branch

Solution (Linux)

I need a command that checks if a branch is merged into master and if it is merged, it should get deleted locally.

1. git checkout master (or whatever branch you want to compare to)
2. git branch --merged | egrep -v "(^\*|master|dev)" | xargs git branch -d

Explanation

1. git branch --merged: List all branches whose tips are reachable from the specified commit (HEAD if not specified).
2. egrep -v "(^\*|master|dev)": Search for all lines that do not start with * (= the current branch), or don’t have master or dev in it.
3. xargs git branch -d: Execute the command to delete all found branches from step 2.
