ls (List): The ls command in Linux is used to list the contents of a directory. It displays files, directories, and their attributes, such as permissions, ownership, size, and modification time.

Common Options:
ls -l: Displays detailed information (long format), including permissions, number of links, owner, group, size, and modification date.ls -a: Lists all files, including hidden files (those starting with a dot.).ls -h: When used with-l, shows file sizes in human-readable format (e.g., KB, MB).ls -R: Recursively lists directories and their contents.ls -t: Sorts files by modification time, with the newest files first.
Example:
ls -lah- This command lists all files, including hidden ones, in a detailed format with human-readable file sizes.
