How can I run a function from a script in command line?

Question

I have a script that has some functions.

Can I run one of the function directly from command line?

Something like this?

myScript.sh func()

Edit: WARNING - seems this doesn't work in all cases, but works well on many public scripts.

If you have a bash script called "control" and inside it you have a function called "build":

function build() { 
  ... 
}

Then you can call it like this (from the directory where it is):

./control build

If it's inside another folder, that would make it:

another_folder/control build

If your file is called "control.sh", that would accordingly make the function callable like this:

./control.sh build
