bash and functions [Solved]

[phunni]

OK, I'm trying to write a bash script - so I googled a couple of tutorials and got started. The first thing I wanted to do was to write a simpel function - all the tutorials seemed to suggest I could.

 

So, to test the concept I wrote the following:

 

#!/bin/bash
echo "Thanks for coming..."
finish

function finish() {
 echo "done..."
 EOF
}

 

When I attempt to run this I get:

 

Thanks for coming...
./myuwefit.sh: line 8: finish: command not found

 

So, what am I missing here...?

It seems that

The function definition must precede the first call to it. There is no method of "declaring" the function, as, for example, in C.

(from the advanced bash guide).

 

So it checks it line by line, and when you call it, it doesn't know what it is. If you define it and then call it, then it knows what to do. ;)

Amazing what small, but crucial, things you can so easily miss...

 

Thanks - that's solved it...
