When are file sizes shown in bytes?

File sizes are shown in bytes when the -h option is not used with the ls command. By default, when you run ls -l, the sizes are displayed in bytes.

Example:

When you run:

ls -l

The output might look like this:

-rw-r--r-- 1 user group 1234 Jan 01 12:00 file.txt

Here, 1234 indicates the file size in bytes.

When to Use:

• If you want to see file sizes in bytes, simply use ls -l.
• If you prefer a more readable format (e.g., KB, MB), use ls -lh.
