ls -l command in Unix, cannot remember file size : I created a new file on a Unix server. But when I run the ls -l command, I get the following:

-rwxr-xr-x 1 mccorm14 student 49508 Oct 26 11:29 4th


I cannot remember if the file size is block or bytes. If its block, how do I convert it to bytes?

Thank you!
