UNIX Commands

Phew! With the file system out of the way, let's get down to some basic UNIX commands!

Since this is just a basic guide, I will mainly cover the basics commands, like copying, renaming, etc. These will allow you to move around the UNIX environment.

Since most of us will be using UNIX from a shell, let's take a look at what the shell looks like.

Now, the basic command syntax in UNIX is always in this form.

command [options][arguments]

A white space separates the options from the command and each option usually starts with a hyphen “-“. Multiple options can be invoked at one time. For example :-

foo –abc /home/foobar/

Options are pretty self-explanatory. What they do is modify the command when invoked. As for arguments, they determine what the command does to the argument.
