Why is the -h option useful when using the ls command?

The -h option is useful when using the ls command because it displays file sizes in a human-readable format.

Benefits:

• Readable Sizes: Instead of showing sizes in bytes (which can be large numbers), it converts them into more understandable units like kilobytes (KB), megabytes (MB), or gigabytes (GB).
• Easier Interpretation: This makes it easier to quickly assess the size of files without needing to do mental conversions.

Example:

When you run ls -lh, the output might look like this:

-rw-r--r-- 1 user group 1.2K Jan 01 12:00 file.txt
drwxr-xr-x 2 user group 4.0K Jan 01 12:00 directory

Here, 1.2K indicates 1.2 kilobytes, and 4.0K indicates 4.0 kilobytes for the directory, making it much clearer than just showing the raw byte count.
