One is by using argument variables and another is by using The main script file name is stored in $0 which receives argument values from command line arguments. If two arguments are passed in command line then the argument values will be received in $1 and $2 variables sequentially. Example -1: Sending three numeric values. $ alias wrap_args='f(){ echo before $@ after; unset -f f; }; f' $ wrap_args x y z before x y z after You can replace $@ with $1 if you only want the first argument. Explanation. This creates a temporary function f, which is passed the arguments. Alias arguments are only passed at the end. Note that f is called at the very end of the alias $0 is the location of the bash executable, and the other parameters have no value. Now let's change shift 0 to shift 1. Open the script in your text editor and change the second line so the script looks like this: $!/bin/bash shift # same as shift 1 echo 1: $1 echo 2: $2 echo 3: $3 echo 4: $4. Everything after the hash mark (#) on line 2 is a comment, and is ignored when the script runs.

If you pass immutable arguments like integers, strings or tuples to a function, the passing acts like call-by-value. The object reference is passed to the function parameters. They can't be changed within the function, because they can't be changed at all, i.e. they are immutable. It's different, if we pass mutable arguments. They are also passed by object reference, but they can be changed in. These two arguments get passed to ls and then acts on them accordingly. Let's simulate this in a script.
