How to know which parameters to use with a command?
In GNU/Linux you can usually issue a command with '--help' parameter, which will display a help page for you. If not, try '-h', '-H', '-?' or none parameters.
You can read man(ual) pages with:
$ man <command or keyword>
If you're not sure what you're looking for, try:
$ apropos <search term>
If you don't know what a command does, there is:
$ whatis <command>
and on Arch Linux (for packages):
$ pacman -Qi <packagename>
on Debian-based distros that would be:
$ apt show <packagename>
For online man pages check 'info' command, it seems to work just like 'man'.
If you don't know where a certain program is, you can use:
$ whereis <name>
If you're still clueless STFW.
STFW = Search the Friendly Web
Try to avoid proprietary search engines like Google or Bing if you can.
