Maybe it is just me, but i sense a misconception about how Unix commands work.
In fact not ls -l does it, but ls does it. "ls" is a command and it shows a directories contents. How it does this can be widely influenced by using certain options.
You already saw the "-l" option at work, which changes the display format from the default short (only filenames) to a long (filemode, owner, group, etc.) listing.
Now, here is a general rule for working with Unix: nobody knows ALL the options every command has - not a single person! This is what "man" pages are for, which you invoke by
man <command>
Think of these as like a telephone directory: you don't have to know all the numbers by heart, you just have to know the name and the city. In Unix you have to know that "ls" shows directories contents and to find out how you manage to get some specific listing of these contents you look up the man page if you can find something which suits your purpose.
So i suggest you try that and report back here. If you find anything worthwile we will take it from there.
I hope this helps.
