Most commands can be modified using
one or more options. Options are used to modify the behavior of the command, such as
to indicate whether the command will produce an output.
Options are usually a single character and are preceded with a dash (such as -h). Some
commands though allow complex options that are complete words. These options are
preceded by a double dash (such as ??”help). If there is more than one option, each can be
listed either separately on the line (such as -a -b -c), or if they are single letter options,
they can all be bunched together after a single dash (such as -abc).
Following the options, there may or may not be one or more arguments for the command
to use. An argument provides information for the command, such as file names to copy
or user accounts to add. Knowing what commands require what arguments can be tricky.
Fortunately there is help in the man pages.
The man Pages
One great feature that openSUSE includes by default is the man pages for Linux
commands. Don??™t worry??”the man pages aren??™t a guy thing. They??™re the manual pages for
all of the commands used in bash.
