The command git stash -u is used to save the changes made to your working directory temporarily without committing them.

Here's what each part of the command means:

• git stash: This is the main command to save changes in the working directory that are not ready to be committed. It creates a new stash object that stores both tracked and untracked changes.
• -u or --include-untracked: This is an option that tells Git to include untracked files in the stash. By default, only the changes in tracked files are stashed. The -u flag allows you to stash untracked files as well.

The purpose of using git stash -u is to store your current changes, including both modified and untracked files, so that you can switch to a different branch or perform other operations without committing or losing your progress. Later, you can apply or pop the stash to retrieve your changes and continue working on them.
