# List of branches to exclude (separated by spaces)
EXCLUDE_BRANCHES=("main" "develop" "release")

# Add the current branch to the exclude list
CURRENT_BRANCH=$(git branch --show-current)
EXCLUDE_BRANCHES+=("$CURRENT_BRANCH")

# Skip branches matching the exclude patterns and delete the rest
for BRANCH in $(git branch | sed 's/* //'); do
  if [[ ! " ${EXCLUDE_BRANCHES[@]} " =~ " ${BRANCH} " ]]; then
    echo "Deleting branch: $BRANCH"

# List of branches to exclude
