Linux Chmod Command Cheatsheet

Use this cheatsheet to find out the meaning of a given chmod command. Understand how each command translates into filesystem permissions.

The chmod command is used to set permissions for files and directories in a Linux system. It supports an octal permission format that is translated into read (r), write (w) and execute (x) permissions for user owner, group owner and others.

If you want to learn more about the meaning of a specific chmod command I have written a tutorial about the chmod 755 command.

The commands in this cheatsheet are split in pages:

• chmod 0xx commands (this page)
• chmod 1xx commands
• chmod 2xx commands
• chmod 3xx commands
• chmod 4xx commands
• chmod 5xx commands
• chmod 6xx commands
• chmod 7xx commands
