Creating Custom Commands

• In most shells, aliases (, , ) are an easy way to shorten a long command line or do a short series of commands.
• All except the oldest Bourne-type shells have shell functions (). These are a cross between aliases and shell scripts. They're good both for shortening command lines and for running a short or long series of commands.
• You can simulate shell functions () on older Bourne shells. These "fake functions" don't have much more power than aliases - but they're better than nothing!
