Linux Command Alias
Most Linux users are well versed in the typing out of lengthy commands in the Terminal. They’re especially hardened and generally insured against such sudden lapses in concentration, where they have to go back mid-command to correct an error.

The rest of us, however, have to deal with the fact that an error is inevitable and that we more often than not have to enter the command again to get it working correctly. There is another option available for Linux users, though. Instead of constantly or frequently having to tap out the complex line of instructions, we can instead use an Alias.

The Alias command isn’t just for Linux; there are examples of it being used via the DOS Key command in the past with DOS and earlier versions of Windows, and more recently appearing in the Windows PowerShell. However, it was introduced back in the old UNIX days and made life significantly simpler for the users of the time.
