Hi,
I use this command :
@wUserInfo=`cocdir -u $wUserId` ; in my CGI perl program.
The problem is if the command "cocdir" find nothing,
It produce an "server error" message. How can I do
to know if it found nothing or do another command
before the program generate the web page that
display the "server error" message.

Thank.

It doesn't work.
Here are the message error :
-----
Server Error

This server has encountered an internal error which prevents it from fulfilling your request. The most likely cause is a misconfiguration. Please ask the administrator to look for messages in the server's error log.
-----
Any code after this line of code won't work
@wUserInfo=`cocdir -u $wUserId` ;

event "exit;"

So I need something inside this line of code
@wUserInfo=`cocdir -u $wUserId` ;
to prevent the browser to display the server error
message above. ex: die, etc...

Thank.

I suggest looking at

ftp://ftp.uni-hamburg.de/pub/soft/lang/perl/CPAN/doc/FAQs/cgi/idiots-guide.html
http://reference.perl.com/query.cgi?cgi

to get some general understanding of how CGI works. Inspite of the name - the first link
is great!

If if( $wUserInfo[0] =~ /server error/ ) doesn't work,
if( $wUserInfo[0] =~ /server error/i ) probably will do.

Best regards, Kai.

It doesn'r work.
How can I use a condition "IF" under the code
line
@wUserInfo=`cocdir -u $wUserId` ;
if the browser has already generated the web
page server error message ?
That mean it not pass throught this line of code
@wUserInfo=`cocdir -u $wUserId` ;
So how can I do to stop it ? may be with "die" ? or
???

What does your CGI program do if you comment out the
# @wUserInfo=`cocdir -u $wUserId` ;
line?
And did you look for messages in the server error log?

#or try adding this to the top of your script:
open (STDERR, ">&STDOUT");
print "Content-type: text/plain\n\n";
