Script to delete branches older than 6 months old, ignore local vs remote errors.

delete_branches_older_than.sh

#!/bin/sh

ECHO='echo '
for branch in $(git branch -a | sed 's/^\s*//' | sed 's/^remotes\///' | grep -v 'main$\|develop$'); do
  if ! ( [[ -f "$branch" ]] || [[ -d "$branch" ]] ) && [[ "$(git log $branch --since "1 month ago" | wc -l)" -eq 0 ]]; then
    if [[ "$DRY_RUN" = "false" ]]; then
      ECHO=""
    fi
    local_branch_name=$(echo "$branch" | sed 's/remotes\/origin\///')
    $ECHO git branch -d "${local_branch_name}"
    $ECHO git push origin --delete "${local_branch_name}"
  fi
done

Yes It can be added.

Will this detect any recent updates to the branches or will it base the age by the date the branch was created?

this will delete based on the latest commit timestamp (note the --since flag). if you want to delete based on branch creation date you should change the flag to --before.

Great. Thanks

this script is not deleting the branches from remote repo, i ran it's executed completely and then count is same on remote branch
