Linux Shell Script Input

I'm trying to tell a shell script information this way (when I execute it via SSH):

bash myscript.sh 'input1' 'input2' 'input3'

However I've no idea on how to convert the inputs 1, 2 and 3 into variables in shell script, like $var1, $var2 and $var3.

Anybody know how?

Its very simple, the arguments passed are held in their respective numbers:

input1 would be on $1
input2 would be on $2
input3 would be on $3

And if I recall it correctly $0 is the script path/filename

And you can for example do this:

#!/bin/sh

echo "arg1='$1' - arg2='$2' - arg3='$3'"
var1="$1"
var2="$2"
var3="$3"
echo "var1='$var1' - var2='$var2' - var3='$var3'"

Not really needed but just to illustrate.
