April 3, 2012 | By Duchateaux.

The Terminal Command Aliases are Very Useful to Register the Long, Repeated or Complicate Commands.
They are meant to Quick Executing Commands by simply Calling a synthetic Label or Name.
So every time you “call” the Alias Name on a Terminal window your action will Correspond to the Sequence of Commands Linked to the Label.

  • The User Aliases are Defined inside the ~/.bashrc, ~/.profile, ~/.bashrc, ~/.shrc, ~/.cshrc.

    • The System Aliases instead are Define into the /etc/bashrc, /etc/profile, /etc/bash.bashrc Files.

Generally the definition of an Alias can be Resumed with:

$ alias ALIASNAME="COMMAND'S SEQUENCE"

And it execution with:

$ ALIASNAME

will Correspond to execute:

$ COMMAND'S SEQUENCE
