What are common ls command options?

Here are some common options for the ls command:

1. -l: Lists files in long format, providing detailed information such as permissions, owner, size, and modification date.

   ls -l

2. -a: Includes hidden files (those starting with a dot) in the listing.

   ls -a

3. -h: When used with -l, it displays file sizes in a human-readable format (e.g., KB, MB).

   ls -lh

4. -R: Recursively lists all files and directories in the current directory and its subdirectories.

   ls -R

5. -t: Sorts files by modification time, with the most recently modified files listed first.

   ls -lt

6. -S: Sorts files by size, with the largest files listed first.

   ls -lS

These options can be combined for more specific listings, such as ls -la to show all files in long format.
