Re: Re: Why do I need -w in a cgi script

Excellent answer. I would not have thought of the "/usr/bin/perl^M", but it makes perfcet sense.

I work in a Windows and Unix environment. One of the most simple yet useful things I've ever found on perlmonks was a slightly different version for stripping the ^M's. I use it all the time and it's very nice if you have multiple files that need cleanup.

perl -pi.bak -e 's/\cM//g' *.cgi

You don't really need the backup up, but it's nice when you first try it to know that you won't lose your data if it doesn't work.

I work in a Windows and Unix environment. One of the most simple yet useful things I've ever found on perlmonks was a slightly different version for stripping the ^M's. I just ssh into the server and edit the files directly there, but for a more production-oriented environment I can see why some might not favor that approach, as a mis-edit could leave the script broken for a couple of minutes. In my situation this is not a big deal. Of course, if it were, I could have two directories on the server, one for development and one for production, which is probably what I'd do. Or have two servers. `$;=sub{$/};@;=map{my($a,$b)=($_,$;);$;=sub{$a.$b->()}} split//,".rekcah lreP rehtona tsuJ";$\=$ ;->();print$/` [download]	[reply] [d/l]
