How do i use arguments in my shell script?

Arguments to a shell script are what you pass it when you run the script. These are called Positional Arguments.

For example, $0 means the script itself, the name of the script on the command line is $0.

The next and first positional argument would be $1, There's also $2, $3, etc

The script we want to run is as follows. nothing complicated here. We are passing the argument $1 to the script.

$ cat myfruit.sh 
#!/bin/bash
echo My favourite fruit is $1

The result after running the script is:

$ myfruit.sh pineapple
My favourite fruit is pineapple

On line one I provided the positional argument for $1 as pineapple.
