What does the -h option do in the ls command?

The -h option in the ls command is used to display file sizes in a human-readable format.

Key Features of -h:

• Readable Sizes: When used with the -l option (i.e., ls -lh), it converts file sizes from bytes into more understandable units such as kilobytes (KB), megabytes (MB), or gigabytes (GB).
• Easier Interpretation: This makes it simpler for users to quickly assess the size of files without needing to mentally convert large byte values.

Example:

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

-rw-r--r-- 1 user group 1.5K Jan 01 12:00 file.txt
drwxr-xr-x 2 user group 4.0K Jan 01 12:00 directory

Here, 1.5K indicates that the file size is 1.5 kilobytes, making it much clearer than just showing the raw byte count.
