Combining bash aliases and arguments/parameters

Question

Let's say I have a bash script called script.sh and I want to create an alias runscript. Now, I know how to create an alias in my bash_profile or bashrc.

However - if I want to run parameters and do the following

$ runscript param1 param2

Is there something special I need to write in the script or in the alias that allows me to run the alias and the use parameters as well?

An alias cannot admin multiple parameters. In case of need, you can create a function to handle them, also in `.bash_profile` or `.bashrc`. — fedorqui, Apr 02 '14 at 12:01
if your params going to the end of line, simple try `alias bubu=ls` and you can `bubu /etc /bin` for `ls /etc /bin` — clt60, Apr 02 '14 at 12:07
not really, because I said everything. if you do `alias bbb=ls` mean the `bbb` will be alias to `ls`. So when you run `bbb arg1 arg2` it is the same as `ls arg1 arg2`. For more advanced argument handling you should use shell functions, as told you already @fedorqui. You should always try the example and will see yourself. ;) — clt60, Apr 02 '14 at 12:59

Based on your other question - "Accessing Shell parameters inside functions" - here is an example:

$ ls script
script
$ cat script
#!/usr/bin/env bash

_aFunction() {
    echo "Parameter 1: ${1}"
    echo "Parameter 2: ${2}"
}

_aFunction
_aFunction "$1" "$2"
_aFunction One Two

$ alias my_alias="./script"
$ my_alias 1 2
Parameter 1:
Parameter 2:
Parameter 1: 1
Parameter 2: 2
Parameter 1: One
Parameter 2: Two
