Other CGI/Perl scripts work fine for me under Apache. Also, once this happens, issuing "apache -k shutdown" no longer closes my Apache console window--I have to kill it manually.
I can execute Perl scripts at the command line on my machine, and the "system" calls execute normally--I only run into trouble when I try to do the same thing through CGI under Apache 1.3.9. I'm using ActiveState Perl (build 520). This is my first experience with Apache, so I can't comment on the behavior in previous versions of Apache. Also, I believe that someone would have reported this already, but I was unable to find it in the bug database. >How-To-Repeat: Just run any Perl script through CGI under Apache 1.3.9 Win32 with a line like: system "del testfile"; It works if you run it at the command line, but fails when invoked via CGI. >Fix: A temp fix for deleting files is to use Perl's "unlink" command in your CGI scripts. However, this doesn't help for system commands other than "del". >Audit-Trail: >Unformatted: [In order for any reply to be added to the PR database, you need] [to include <[EMAIL PROTECTED]> in the Cc line and make sure the] [subject line starts with the report component and number, with ] [or without any 'Re:' prefixes (such as "general/1098:" or ] ["Re: general/1098:").
