Hello, I'm new in Perl programming and I think that this is an easy question for you:
I'm using Apache 1.3.26 and Perl 5.5.3 and I don't want to install additional modules if I can avoid it. I have an script, ex. test.pl that must control if it is already executing, and if it is, it must wait for some seconds. I don't want to use Proc::ProcessTable or other libraries. I would like to do this with the standard Perl 5.5.3. So, I need to create a global variable (environment variable, etc) and set his value to EXECUTING (1 for instance) when the script begins and change his value to FREE (0 for example) when the perl script finish. Every time that the script begins must check the value of this variable and wait some seconds and try again if the other processes have finished. Is there any easy way to do this without installing extra modules ? Thanks in advance, Enric -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
