[Samba] How do I lock a shared file?

Perhaps you need another tool than a text editor which is designed for  
"one man (m/f), one work". I'd test some wikis for such a job. But then  
still there is the problem with two pupils (or other persons) one  
filling the document and the other deleting word for word.

Programmers for data bases know this problem ...

And just for demonstration: group all pupils around the whiteboard or  
blackboard in the class room, let them create and edit one text on this  
board, everybody with a piece of chalk and a wiping cloth.

Viele Gruesse!
