The general syntax of zypper is:
zypper [global-options] command [command-options] [arguments] ...

zypper patch
Additionally, you can choose from one or more global options by typing them just before the command: (run the command, but don't ask me anything, decide on your own)
zypper --non-interactive patch
To use the options specific to particular command, type them right after the command: (apply needed patches to the system but don't ask me to confirm any licenses, i've read them all before)
zypper patch --auto-agree-with-licenses
Some of the commands require one or more arguments: (install or update mplayer package)
zypper in stall mplayer
Some of the options also require an argument: (search for patterns)
zypper search -t pattern
All of the above combined: (install mplayer and amarok by using the factory repository only, be verbose)
zypper -v install --repo factory mplayer amarok
