Split string into an array in Bash
...tually quite a clever trick, and accomplishes exactly what is required (at least with respect to assignment effectation) in a rather non-obvious way. I'm actually not against this trick in general, despite the involvement of eval; just be careful to single-quote the argument string to guard against ...
How can I lock a file using java (if possible)
...er. How can I prevent another (Java) process from opening this file, or at least notify that second process that the file is already opened? Does this automatically make the second process get an exception if the file is open (which solves my problem) or do I have to explicitly open it in the first ...

To say they least, it's rather complex and when the different methods kick in are subtle.
