# lists branches that can be deleted/pruned on your local. An option --dry-run is needed
git remote prune origin --dry-run

# In order to clean up remote tracking branches, 
# meaning deleting references to non-existing remote branches, 
# use the “git remote prune” command and specify the remote name
git remote prune origin

# remember: git branch –merged” command takes the HEAD when not provided with a commit SHA
git branch --merged | egrep -v  "^\*|main|dev|master" | xargs git branch -d
# or, for unmerged branches
git branch | egrep -v  "^\*|main|dev|master" | xargs git branch -D
