How can I create a parameterized bash alias?

Question

I would like to create a parameterized bash alias. I am not certain that is the correct way to describe it.

For example:

alias gps="gulp protractor --specs=test/browser/specs/<i-want-to-parameterize-this-bit>.js"

So that I can type:

gps foo/bar

...and the command resovles to:

alias gps="gulp protractor --specs=test/browser/specs/foo/bar.js"

How can I do this?

Answer 1

Use a shell function:

gdiff() { 
   git diff --color=always "$@" | less -r
}

Another example:

foo() { /path/to/command "$@" ;}
foo arg1 arg2

You can create script, and pass arg.
