Re: How to run a Perl script from another script?

If "newscript.pl" is supposed to have access to the CGI parameters, this won't happen with just "exec('newscript.pl')" -- you would need to work out a way to convey the params safely via the command line that you pass to exec().

But even if that isn't the issue, I still tend to agree with data64's opinion. You say you "prefer not to do a use or require", but you don't give any specific reason for that. In the absence of any specific reason, I'd say "get over it", and turn "newscript" into a module that your various other scripts can "use".

graff, I appreciate your candor. The reason is that new script is really the more weighty script, basically a full-fledged "program" that I have a hard time thinking of as a merely module. There truly is a transfer of purpose and direction when leaving the one earlier script and going to the new script.

... that new script is really the more weighty script, basically a full-fledged "program" that I have a hard time thinking of as a merely module. Do you mean that sometimes this new script is run entirely by itself, without any prior script being run ahead of it? I wasn't expecting this... Based on the initial question, I assumed that you have several scripts that each produce some distinct beginning portion of a page, and the "newscript" provides a common final portion for all those different pages. If that's what you're doing, then it still seems more sensible as a module, regardless of its size. (On the other hand, if the script really does work on its own without any prior script ahead of it, I'm a little unclear about how you are adapting it to this "secondary" role.) Do you have some different reason for "chaining" scripts in this way? Turning a script into a module doesn't need to involve a lot of fuss. Just put in a "package" statement at the top and a "1;" at the end, and instead of printing to STDOUT, have it accumulate text into a return string. Maybe you'll need a little bit of "reorganization" to have a single sub that returns the string (by doing whatever "main" does in the current version).	[reply]

Yes, it is run on it's own, depending on circumstances. —Brad "Don't ever take a fence down until you know the reason it was put up." G. K. Chesterton	[reply]
