How often do you spend typing same long command again and again. It might just take few seconds but if you sum up it could comsume considerable amount of time over a day, weeks, month and even a year.

On Windows OS there is often a Keyboard Shortcut. But if you are a Linux user relying on the command line then you can use Bash Aliases (command line short cut) instead of typing a long command sequence.

Listed below are some popular and commonly used bash aliases that have been found throughout the web:

Navigation and Listing

//Make ls display in columns and with a file type indicator (end directories with "/", etc) by default:
alias ls="ls -CF"

//We can also anticipate some typos to make it call the correct command:
alias sl="ls"

//for viewing large directory listings with the long format:
alias lsl="ls -lhFA | less"

//Frequently used directories
alias home='cd /home/{$yourUserDirectory}'
alias docs='cd /home/{$yourUserDirectory}/Documents'
alias desk='cd /home/{$yourUserDirectory}/Desktop'
alias www='cd /home/www/'

//Quickly navigate directories
alias ..  ='cd ..'
alias ... ='cd ../..'
alias .4 = ‘cd ../../../../’
alias .5 = ‘cd ../../../../../’

//clear screen
alias c = 'clear'

Git Short Cut

alias gs='git status'
//gpull 
alias gpull=’git pull origin’
alias gpush='git push origin'
alias gpom='git pull origin master'
alias gb='git branch'
alias gc='git checkout'
alias gcm='git checkout master'
alias ga='git add'
alias gA='git add .'
alias gcom='git commit -m'
alias gm='git merge'
alias gl='git log'
alias gcb='git checkout branch'
alias gbd='git branch -d'
//for example gbD branchToBeDeleted
alias gbD='git branch -D'

Extract any kind of archive [zip, rar. tar etc]

//Add below on .bashrc and type "extract " to execute command
extract() {
    if [ -f $1 ] ; then
      case $1 in
        *.tar.bz2)   tar xjf $1     ;;
        *.tar.gz)    tar xzf $1     ;;
        *.bz2)       bunzip2 $1     ;;
        *.rar)       unrar e $1     ;;
        *.gz)        gunzip $1      ;;
        *.tar)       tar xf $1      ;;
        *.tbz2)      tar xjf $1     ;;
        *.tgz)       tar xzf $1     ;;
        *.zip)       unzip $1       ;;
        *.Z)         uncompress $1  ;;
        *.7z)        7z x $1        ;;
        *)     echo "'$1' cannot be extracted via extract()" ;;
         esac
     else
         echo "'$1' is not a valid file"
     fi
}

KIll process by name (does same thing as pKill but with output) kp NAME

kp () {
  ps aux | grep $1 > /dev/null
  mypid=$(pidof $1)
  if [ "$mypid" != "" ]; then
    kill -9 $(pidof $1)
    if [[ "$?" == "0" ]]; then
      echo "PID $mypid ($1) killed."
    fi
  else
    echo "None killed."
  fi
  return;
}

Make yourself look busy and fancy in the eyes of non-technical stupid people

alias busy="cat /dev/urandom | hexdump -C | grep "ca fe""
