Command: ls

Use

ls
ls -la ~

What It Does

ls lists directory entries.

Useful Options

• -a: include hidden dotfiles.
• -l: long listing with type, permissions, owner, group, size, time, and name.
• -h: human-readable sizes when used with -l.
• -S: sort by size.
• -t: sort by modification time.

Long Listing

ls -l ~/src/pages

The first column shows file type and permissions. The owner and group columns matter on a shared server.

Watch Out

ls output is for humans. Scripts should usually use explicit paths, find, or shell globs instead of parsing decorative ls output.

Docs Pointers

• Run man ls.
• Read ls -l, directory, permissions, and path.
