Hello together, I have a question regarding process-control. I want to write a perl script which must not running in more than one process in the same time. The script creates a directory copys a zip-file in it, unpack it and reads every file in this package. However, the files must not get opened by another process. How can I make sure, that my perl-scipt runs only in one process, or eaysier, is there a function "flock" which blocks a whole directory and not only a single file?
