usage_description="
Run a command for each GitHub Actions workflow in the given repo

All arguments after the repo become the command template

WARNING: do not run any command reading from standard input, otherwise it will consume the workflow id/names and exit after the first iteration

\$GITHUB_ORGANIZATION / \$GITHUB_USER - the user or organization to iterate the repos on - if not specified then determines the currently authenticated github user from your \$GITHUB_TOKEN

The command template replaces the following for convenience in each iteration:

{organization}, {org} => the organization account being iterated
{username}, {user}    => the user account being iterated
{repo}                => the repo name with the user prefix
{workflow}, {name}    => the workflow name
{id}, {workflow_id}   => the workflow id

eg.
    ${0##*/} devops-bash-tools echo user={user} repo={repo} name={name} workflow_name={workflow} id={id}
    ${0##*/} devops-bash-tools echo org={org}   repo={repo} name={name} workflow_name={workflow} id={id}
