Script to delete all disabled branches of a Bamboo build plan.

bamboo_delete_disabled_branches.sh

#!/bin/bash -u
# Deletes all disabled branches of a Bamboo build plan
# -----------------------------------------------------------------------------
# Syntax: 
#   $0 {planKey}
# -----------------------------------------------------------------------------
# Purpose: Bamboo does not automatically delete plan branches when the 
#   corresponding branch in the repository gets deleted. Because Bamboo fails 
#   to pull from it, it disables the branch but keep it around forever.
#   This script goes through all branches of a build plan and delete the ones
#   that are disabled.
#
#   Notes:
#      - Script depends on jq library: https://github.com/stedolan/jq
#      - The script will prompt for Bamboo credentials. The corresponding
#        account must have admin access to the given plan.
#      - Before running the script, change the value of `BAMBOO_BASE_URL` to 
#        the correct url of the bamboo instance.

Possible typo at curli -k -qs

function delete_branch {

    echo "delete branch ${branch_key}"
    curli -k -qs --user "$username:$password" --header "X-Atlassian-Token: no-check" -H 'Accept: application/json' -H 'Content-Type: application/x-www-form-urlencoded' --data "buildKey=$branch_key" "$BAMBOO_DELETE_PLAN_URL"

Yes, thank you!

Worked a charm on bamboo 6.5.0. Many thanks!
