Unix help: what does the 'ls -proc' command do?

Question

And is 'proc' standing for something here or is it a bunch of modifiers bunched together?

I'm running ubuntu dapper, I understand what the permissions and users means, but I don't know why these specific files are listed. tia.

Answer 1

From the "man ls" page (in my case from a Solaris 10 system so yours may differ):

-p Puts a slash (/) after each filename if the file is a directory.
-r Reverses the order of sort to get reverse alphabetic or oldest first as appropriate.
-o The same as -l, except that the group is not printed.
-c Uses time of last modification of the i-node (file created, mode changed, and so forth) for sorting (-t) or printing (-l or -n).

"proc" is a group of options.

Answer 2

do a man ls from the command or

go to..

http://www.rt.com/man/
Look up the ls command and it will give you a description.

I logged into my linux machine and here is the output from it. It should be the same in unix.

I did a ls first to look at what is in the directory.
