Make a Bash alias that takes a parameter?

Question

I used to use CShell (csh), which lets you make an alias that takes a parameter. The notation was something like

alias junk=\"mv \\\\!* ~/.Trash\"


        

Answer 1

All you have to do is make a function inside an alias:

$ alias mkcd='_mkcd(){ mkdir "$1"; cd "$1";}; _mkcd'
             ^        *      ^  ^     ^  ^         ^

You must put double quotes around "$1" because single quotes will not work. This is because clashing the quotes at the places marked with arrows confuses the system. Also, a space at the place marked with a star is needed for the function.

Answer 2

You don't have to do anything, alias does this automatically.

For example, if i want to make git pull origin master parameterized, i can simply create an alias as follows:

alias gpull = 'git pull origin '

and when actually calling it, you can pass 'master' (the branch name) as a parameter, like this:

gpull master
//or any other branch
gpull mybranch
