Share variable between functions

Shell Programming and Scripting

Hi,

      gtkdialog gui seperate buttons use seperate  functions in their GUI. A variable \(newFolderName\) is being set in one  function \(funcA\) and it needs to be called in another function \(funcB\). I  thought using global variable \(like in python\) concept should work  however it does not.

How else is it possible to do share variables between functions. ?

Example

funcA() {
	newFolderName=v01
}

funcB() {
	mkdir newFolderName
}

funcA and funcB are called as action to button

<button>
	<label>Confirm</label>
	<action>funcConfirmDisplayText</action>
</button>

<button>
	<label>Start</label>
	<action>funcStart</action>
</button>

change to mkdir $newFolderName

Oops that is already true ( it is actually mkdir $newFolderName )

You can always pass a variable to a function:

funcA(){
  echo "Hello $1"
  funcB v01-$1
}
funcB(){
  mkdir $1
}
funcA Singhai

Will echo "Hello Singhai" and create a folder named "v01-Singhai"

When you define a variable prior to functions, that value will be used.
However, if you define a variable with the same name within a function, that value will remain inside the function.

Not sure if 'special' shopt settings are required or if its regular behaviour.
