What is the 'ls' command?

The ls command in Linux is used to list the contents of a directory. By default, it shows the files and subdirectories in the current working directory.

Common Options:

• ls -l: Lists in long format, showing permissions, owner, size, and modification date.
• ls -a: Includes hidden files (those starting with a dot).
• ls -h: Displays file sizes in a human-readable format (e.g., KB, MB).

Example:

$ ls
file1.txt  file2.txt  folder1

This command will display the names of files and directories in the current directory.
