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 $(git branch -a | sed 's/^\s*//' | sed 's/^remotes\///' | grep -v 'master$'); do
  if [[ "$(git log $branch --since "6 months ago" | wc -l)" -eq 0 ]]; then
    if [[ "$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

1. Note the "DRY_RUN" argument you need to set it to false to actually delete.
2. I see branch names with white spaces, added a minor fix for that.

I like this script but it seems to pick up directories and files ...

    
    ECHO='echo ';
    for branch in $(git branch -a | sed 's/^\s*//' | sed 's/^remotes\///' | grep -v 'main$\|develop$'); do
      if [[ -f "$branch" ]]; then 
        $ECHO $branch;
      fi
    done

I added a directory and file check

  ECHO='echo ';
  for branch in $(git branch -a | sed 's/^\s*//' | sed 's/^remotes\///' | grep -v 'main$\|develop$'); do
    if ! ( [[ -f "$branch" ]] || [[ -d "$branch" ]] ); then 
      $ECHO $branch;
    fi
  done

my full script is here ... note I want to exclude main and develop
