zsh Main differences from bash Aliases


Example

Global aliases

In bash, aliases can only be placed at the beginning of of a command, but zsh supports aliases anywhere. If you place the following line in your $ZDOTDIR/.zshrc

alias -g G=' | grep -i'

You can then run

cat haystack.txt G "needle"

Suffix aliases (Added in zsh 4.2.x)

Suffix aliases allow you to tell zsh to open files with specify a program to open files with certain extensions. Examples:

alias -s c="emacs"
alias -s php="vim"
alias -s java="$EDITOR"

Now in your shell, if you have a php file, file.php, and you run the command

file.php

It will automatically open file.php in vim.
