Is a perpetually running perl script possible?

35 New Member
I have no exprience with perl.

What I'm trying to do is have a script/program constantly (perpetually) running on my server so that it performs a routine (like every hour) and automatic check of something like the current weather in Tokyo and records it.

The catch is that I want this to be done back-end and automatically without someone having to go onto the website and doing a "check" or something. This would mean that the script must be running continuously.

Is this possible at all? Can perl for example run continuously on a (remote) server?

The canonical way to execute a (perl) script at certain times would be to use the cron daemon.

Of course, it would also be possible to program the script itself to execute the check and 'sleep' (Perl has a function of that name) until the next check, but cron is made for such tasks.

Hope that helps.

Thanks, arne. That does answer my question. I wanted to know whether this was possible before I embarked on a dead end.

Peace

Is it possible to run a Perl script from within a javascript? I have an existing javascript that provides some data - and I want to write that data to a text file on my server via a Perl script (that I also already have). Both scripts work great - I just don't know how to make them work together. Is this even possible?
