Code:
unless ( open FIN, "variable.txt" ){
  print "cannot read file: variable.txt\n";
  return;
  }

$line = <FIN>;
chomp $line;
close FIN;

( $junk, $value ) = split( /\=/, $line );

print "VALUE: $value \n";

well.... you have to store the variable you want in a file somewhere.

when you say "CGI", I'm assuming you mean through apache and perl.

What I wrote goes into a script that apache accesses:

No, i haven't defined variable in CGI script, i am using perl and executing script in Linux.
i want to print variable which i have defined at command line using CGI script.

oh...

Code:
$num = 0;
for $arg in ( @ARGV ){
  $num++;
  print "arg[$num]: $arg \n";
  }

In an odd perl quirk, the command itself is: $0

Hi quirkasaurus, Thanks for your reply, but i haven't understood what you are trying to say here, if you will try to explain it to me with consideration of my variables it will help me since i am a beginner to unix & CGI scripting.

THanks in advance.

PHP requires that all variables begin with a dollar sign, for example $flag.
