Bash script to rename the directory a JetBrain's IDE project is contained in (I got tired of waiting for JetBrains to add this obviously needed feature to their actual IDE!)

mv-jetbrains-ide-project.sh

#!/usr/bin/env bash

set -euo pipefail

# Check if both arguments are provided
if [ $# -ne 2 ]; then
  echo "Rename a Jetbrains IDE project"
  echo "Usage:"
  echo "   $(basename "$0") <old_project_name> <new_project_name> [<projects_dir default=~/Projects>]"
  exit 1
fi
