Oh, I see. I'm a bit confused. Maybe it's my fault...
Do you have a string like "display_file.pl?filename=blahblah" or are you
calling the CGI with http://www.domain.it/display_file.pl?filename=blahblah
?
The code I wrote is for the latter...
In the first case, you could use regexes:
#!/usr/bin/perl
$_ = "display_file.pl?filename=blahblah";
m/=(\w+)$/;
$file = $1;
This works quite fine, but it is no good, if the String looks like
http://www.domain.it/display_file.pl?filename=blahblah&sex=yesplease&drugs=j
ustsayno
But I think you got the idea...
No, wait. I got the idea...
m/filename=(\w+)&?/;
should work perfectly...

alenzen::> Hi,
alenzen::>
alenzen::> THis is probably a simple question. Am new to perl and CGI so
please
alenzen::> have mercy. I have a script which displays a list of files with
links
alenzen::> to them. The links when hovered over in a browser show as:
alenzen::>
alenzen::> display_file.pl?filename=blahblah
alenzen::>
alenzen::> How can I extract the blahblah bit (which is the name of the
selected
alenzen::> file) so that the display_file.pl script can know which file it
is to
alenzen::> open and process? I think this makes sence. I want the script
alenzen::> display_file.pl to perform an action on file blahblah.
alenzen::>
alenzen::> TIA

I didn't generate a form - I am obviously mistaken as I was under the
impression that to use the param call then a form had to specify it.
Boy have I got much to learn.
Cheers
Francesco
