You can do ‘ls -l‘ to get a detailed directory listing like this:

-rw-rw-rw-  1 alice themonkeys 1159995999 2008-08-20 07:01 foo.log -rw-rw-rw-  1 bob   bob         244251992 2008-08-20 05:30 bar.txt

But notice how you have to slide your finger along the screen to figure out the order of magnitude of those file sizes.

What’s a good way to add commas to the file sizes in the directory listing, like this:

-rw-rw-rw-  1 alice themonkeys 1,159,995,999 2008-08-20 07:01 foo.log -rw-rw-rw-  1 bob   bob          244,251,992 2008-08-20 05:30 bar.txt

  1. I don’t think ‘ls’ has exactly that capability. If you are looking for readability, ‘ls -lh’ will give you file sizes that are easier for humans to parse.
