Alias command definition:

Alias is a built-in shell command that allows you create shortcuts/synonyms for other shell commands.

How to make an alias:

• Sintax

alias [name=['command']]

• example - make an alias for clear command:
  

$ alias cl='clear'

• description: now when you type cl at your terminal, is the same thing as type clear. This can be used for more and/or long stings..
• other alias:

$ alias p='pwd'

$ alias x="exit"

$ alias folderx='cd /home/your_user/Desktop/folderx'

How to remove an alias:

• Sintax

unalias [alias_name]

• example - remove an alias for clear command:
  

$ unalias cl

Note:

When the computer is rebooted all alias will be lost.
How to prevent it? All alias must be added to .bashrc file located at your user folder (example: /home/uterrorista/.bashrc)

• example:

$ gedit /home/uterrorista/.bashrc

• paste:

alias cl='clear'
etc...

• now you have to 'compile' your .bashrc file

$ source .bashrc

• Now cl alias it's saved..

My tutorial:

Make an alias to create other alias..

• Edit .bashrc

$ cd
$ gedit .bashrc

• and paste (replace your_user_name with your nick session):

## Add new alias and compile i
alias aalias='gedit /home/your_user_name/.bashrc && source /home/your_user_name/.bashrc'

• compile

$ source .bashrc

• Now you can add the alias you want just simple doing:

$ aalias

• add (for example. you can make now your desired alias):

## One folder up
alias up='cd ..'

## Clear screen
alias cl='clear'

alias ff='find . -name $*'
alias untar='tar zxvf'
alias p='pwd'

alias ls="ls --color=auto"
alias ll="ls -l --color=auto"
alias la="ls -l -a --color=auto"

alias x="exit"

alias compilar='sudo ./configure && sudo make && sudo make install'

alias apti='sudo apt-get install'
alias aptud='sudo apt-get update'
alias aptug='sudo apt-get upgrade'

alias aptar='sudo apt-get autoremove'
alias aptr='sudo apt-get remove'

alias aptc='sudo apt-get clean'
alias aptac='sudo apt-get autoclean'


function today {
echo "Today's date is:"
date +"%A, %B %-d, %Y"
}

• Note: you if have noticed i have a function on my .bashrc file - function today. To run it type: today.
  

• to remove an alias: just edit the .bashrc file (aalias) and remove/delete the alias you don't need anymore..
