Exceuting function in Shell file from command

In my shellFile.sh I wrote this function:

#!/bin/bash
myFunction(){
echo 1
}

I tried to call the function from the command line this way:

shellFile.sh
shellFile.sh myFunction

After this two lines there is no output and no errors. I apologize if this question is asked before but I couldn't find it.

I suggest:

#!/bin/bash
myFunction(){
  echo 1
}

$1

Usage: ./shellFile.sh myFunction

Output:

1

If you want the function to be available from the command line, you need to create the function in the current shell, using the dot . command, or in Bash its workalike source:

$ . shellFile.sh
$ myFunction
1
$

You need to call the function in the script:

#!/bin/bash
myFunction() {
    echo 1
}
myFunction

you can call your function inside your script like this

#!/bin/bash
myFunction(){
echo 1
}

myFunction

If you want to use the function interactively you can source the script, then call the function from the command line.

$ source shellFile.sh
$ myFunction
1
