Make a file executable

Quest: make-file-executable

Mission

Create a harmless playground file and make it executable.

Commands You Will Use

• touch
• chmod
• ls -l

Steps

1. Run touch ~/playground/permission-test.txt.
2. Run chmod u+x ~/playground/permission-test.txt.
3. Run ls -l ~/playground/permission-test.txt and confirm the owner triplet has x.
4. Run guide check to check the file and executable bit.

Hints

1. chmod u+x adds execute permission for the owner.
2. ls -l should show an x in the owner triplet.
3. The file does not need script content yet. S5 teaches shebangs and scripts.

If Check Fails

Rerun chmod u+x ~/playground/permission-test.txt, then check the owner execute bit with ls -l.
