Part 10 Introduction To Bash - Functions

The first arg pass on the terminal is $1, I also saw that the same was done for the first arg of a function. How do I differentiate between the two (when does, $1 refers to first arg from terminal and func

Hi there, very good question!
The file argument $1 will not be available inside your function. So if you want to pass your $1 argument to your function you need to add it after the name of the function when calling it.
Here is an example script to test with:
```
#!/bin/bash
echo "Argument " ${1}
function test(){
echo "Function Argument: " ${1}
}
test Fun
```

@@bobbyiliev_ assuming you do, `bash filename.sh Bobby` the output will be `Argument Bobby`
`Function argument Fun`
But `${1}` was used for both which made me confused a little. Thanks for the clarification
