Bash script to list git commits by Linear ID

As we're switching from PT to Linear, I've updated the existing bash script to work for commits that are referencing Linear IDs.

A core benefit of our convention to prefix commits by their corresponding issue ID is that we can easily detect commits that belong to the same issue. You can either do that manually or use the bash script below. It can either be placed in your .bashrc or any location that is loaded by it.

# Usage: linearcommits FOO-123456
# Alternative usage: linearcommits https://linear.app/some-workspace/issue/FOO-123456
function linearcommits {
  if test "$1"
  then
    local LINEAR_ID=$(echo "$1" | grep "[^/]*$" -o) # Extract linear ID from URLs
    git log --oneline --grep $LINEAR_ID | grep "^[a-z0-9]*" -o | xargs --no-run-if-empty git show $2 $3 $4
  else
    echo "Please specify a Linear issue ID"
  fi
}

alias linearcommit='linearcommits'

Now you can use use the command with up to three arguments (just like a regular git show).
Example output for linearcommits ABC-165086636 --stat:
