Thread: Using Alias command in Linux

To generate helpful shortcuts of ready command line I would like to utilize alias command. But I didn’t have much information about it so please tell me how to use this command and drawbacks of it. Also tell me about shred command.

An alias is command defined by user, which call other command. His interest lies in chance to utilize shortcuts for commands with many options that utilize often. To utilize earlier example, command shred it was needed to remove file by rewriting over 50 times and writing zeros earlier than Suppress, enter following command - shred -uvz -n 50.

As a result of aliases we able to decrease number of characters to entered to permit execution of command. To make alias of shred command with -n UVZ-50, continue as follows alias del=shred shred -uvz -n 50. Here del is alias of command shred with options specified. You can check alias now and see effect.
