9.3) Redirection

Joining files together is not that much use if the results could only be printed to the screen. The real power of commands like ‘cat’ and other commands is to have the output directed into a new file instead of the screen.

You can store the results of Unix commands (such as cat, ls, etc or any other command) by using the redirection command, ‘>’, at the end of the cat command. This redirection is used extensively in Unix and can be used after almost all commands.
