Basic Information

What is this command?

rm is an abbreviation for remove, a command that deletes files or directories from the file system. Since Linux's rm has no trash concept and permanently deletes immediately upon execution, caution is required.

Deleting directories requires the -r (recursive) option, and the -f option can skip confirmation prompts.

What problem does it solve?

• Deletes unnecessary files.
• Deletes directories and all their contents.
• Cleans up temporary files.
• Frees up disk space.
