alias gs='git status'
alias ga='git add -A'
alias gc='git commit -a -m $1'
alias gp='git push origin master'
alias gpl='git pull origin master'

After saving the file, restart the command prompt. Type the alias in the command prompt to get the results:

• Git Status:

  gs

• Git Add:

  ga

• Git commit:

  gc "your message"

• Git Push:

  gp

• Git Pull:

  gpl

*Note:
$1, $2, $3, etc… are command line inputs which are passed to alias.
Same way you can also use this feature in Git Push & Git Pull to treat command line inputs as sources and branches
