How do I check the size of a file in Linux?
Using the ls Command
- –l – displays a list of files and directories in long format and shows the sizes in bytes.

What is the unit of file size in Linux?
In ls long listing format, by default the file size unit used is bytes. But, you can easily change that with the –block-size option of ls. To set the unit to petabytes, use –block-size=P. As you can see, the file sizes are printed in megabyte unit.
What is the file size in UNIX?
