How to create short-cut or alias of linux or unix command ?

Usually we use lot’s of command in our daily work. Using those same command more and more time. By using some alias or command we can easily handle those commands

What Are Aliases?

Aliases are shortcuts refer to commands. For example (and a dead simple one at that), if you use Terminal to do anything, like open hosts file with vi , we probably uses

sudo vi /Applications/MAMP/conf/apache/extra/httpd-vhosts.conf

But after making alias i just use vhostEdit .

alias vhostEdit='sudo vi /Applications/MAMP/conf/apache/extra/httpd-vhosts.conf'

Usefulness of making command Alias

1. We can speedup our works
2. No chance to forgot the command structure just need to remember the short-cut
3. You can hide your secure information into the command alias.

How to make alias or command ??

alias gr="git rebase"
alias gl="git log --oneline --decorate --graph"
alias glog="git log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --"
alias glga="git log --graph --oneline --all --decorate"
alias gb="git branch"
alias gs="git show"
alias gd="diff --color --color-words --abbrev"
