To make the script callable globally as create_feature_branch, you can follow these steps:

1. Save the Bash script to a directory that is included in your system's PATH.
2. Rename the script file to create_feature_branch (without the .sh extension).
3. Make the script executable using the command chmod +x create_feature_branch.
4. Refresh your system's PATH to ensure it recognizes the new script.

Once you've completed these steps, you can run the script from any directory by simply typing create_feature_branch in the terminal. The script will then prompt you for the name of the new feature branch and create it accordingly.
