in reply to redirecting stdin on windows

What you're asking to do doesn't require Perl at all - the shell can already do it. Create a text file with the username on one line and the password on the next <insert speech about how you shouldn't store passwords in plaintext>. Then, you can simply do myexe.exe < answer.txt where answer.txt is the "answer file" you created.

If you really wanted to get Perl involved for some other reason, you could do this same thing from a call to system.

    I tried doing

    command < input_file

    but it only works if the command asks for one input entry, in windows.

      Funny, it works for the following (on WinXP):

      script.pl
      print "username: "; chomp ($uname = <STDIN>); print "\npassword: "; chomp ($password = <STDIN>); print "\nYou entered username $uname and password $password\n";
      answer.txt
      someusername somepassword
      And I'm calling it like this:
      perl script.pl < answer.txt
      ...which produces this:
      C:\test\scratch>perl script.pl < answer.txt username: password: You entered username someusername and password somepassword
      ...which is the expected output.
