Re: need help to passing argument to executable and get return the result

in reply to need help to passing argument to executable and get return the result

You can call an executable installed on your system by using `script path`, and you can pass it a value by doing `script path arguments`. The script (if it's Perl) can then access these arguments the regular way, through @ARGV, and print a result, and you should be able to access the result if you did $var = `script path arguments`. I'll go test this now and see if my memory works properly :)
## print.pl my $arguments = 'beep'; my $var = `perl process.pl $arguments`; print $var;
## process.pl my $var = shift @ARGV; $var = uc($var); print $var;
If I do perl print.pl, I get the result BEEP, which means it's passing back and forth properly.

    Thanks TedPride it was really very helpful.
    can you solve one more thing?
    if there are four argument then how will process.pl handle it?
    Thanks again
      ted pride i used ur code it is working properly.Thanks
      but i got error when i pass both parameter but one is blank so this code could not handle that condition and i trapped in this.
      $output='xyz.pl $param1 $param2'; where $param1=''; $param2=0;
      i'm not getting how can i handle it.
      my ($x,$y)=@argv;
