Command prompt/terminal flags

[Lopezadl2ian]

Hello,

I don't know to much about the terminal and I am trying to learn more about using the terminal in Linux.
I was wondering if there was a resource sheet that explained what all the flags mean and or what each of them can do. Example: -l, -t, -r etc. I was trying to use Goggle to find some resources but could not find anything related other than bash commands which did not list all the flags. Maybe the term is not flag? Any help would be appreciated. Thanks.

Each command has different options (what you call "flags") which could mean different things, based on the command. To see a fairly comprehensive list of Linux commands, look here. You could also see what those options mean by viewing the manual page for that command. For example, to what all the options for the "ls" command are, do this:

man ls

You move forward in the man page by hitting the spacebar, move backwards by hitting b, and you quit the viewer by hitting q.

Some commands use the "info" format for their manuals. For example, the ls command has a more detailed info manual than the standard "man page" format, so you could also do this:

info ls

You can navigate the info pages the same way as the man pages, though info pages have sort of a hyperlink feature that man pages don't have. You can use the pinfo viewer to use those (the arrow keys can be used to follow the hyperlinks). If you don't have pinfo installed, install it like this:
yum install pinfo

For now, I'd recommend just using the man command to see the basic information.

Excellent! Thank you!
