Combination Of commands
Hello All,

I just wanted to know what are the different ways of using commands in combination.

The most common one which i know is using pipes.
Also grouping is also done like ( ls; date) where output of both the commands is displayed.

Are there any other ways of combining various commands and using them on command line or in the scripts.

Thanks,
Rahul
