Linux – the default size unit in linux ls -l command

linux

I wanted to know what is the unit(bytes, bits, kb) of the output of the ls -l command in Linux. Here is an example of what I've got :

-rw-rw-r--    1 guest    guest       39870 Feb 14 19:41 ser_cat
-rw-r--r--    1 guest    guest       19935 Feb 14 19:35 ser_cp
-rw-rw-r--    1 guest    guest       19935 Feb 14 19:29 ser_more

I wanted to know what is the unit of 39870 (the size of ser_cat)?

Best Answer

That size is in bytes.

You can use ls -lh to print the long listing with human readable file sizes.
