Hi, i am newbie to perl and coded a small perl program with the below objective as follows:

• 1. Triggering another script(ThirlPartyScript.start) from this perl.
• 2. Directing the output of that script in a file such that only those lines are stored which match a string.
• 3. Mail the file generated at the step 2.

I am able to achieve the above objectives on a test script. But ThirlPartyScript.start after completion expect some inputs and hence user interaction, so when i call this script from my perl code, it never completes as it seems to be waiting for that user interaction to complete. below is the code i am using to execute that third party script:

#Run the command    
open( CMD, "$run_cmd|" ) || die "Not able to run \"$run_cmd\":$!\n"; 
    while( <CMD> ){      # read command's output from the pipe
         # do write to file with what we read back from the proces
        print $fh_cmd_in $_;
      
    }

Can someone let me know how to supply that iterative argument when calling a script from perl so that the called script completes? Thanks
