Create Alias Command with Parameter in Linux

"Alias" - A shortcut for a command or set of commands

Linux OS provides the facility to have alias command to keep the long and frequent command to very few keystrokes, May be I am being a more cryptic with the lots of jargon words, let's try to understand this way -

When you execute a command "ll" (double Ele) in Linux prompt, it will return the result which is the same as "ls -l" because most of the modern linux os have this alias command (ll) for "ls -l" which is quick and easy.  You can add your customize command in ".bashrc" (dot bashrc) in case of  BASH shell or ".kshrc" in case of KORN shell.

How To:
alias pcs = 'ps -ef'  # this will create an alias named pcs which is equivalent to "ps -ef"

As we can see, we can create lots of alias of frequent commands needed in our day to day work, but avoid the alias which modifies/delete system files.
