How do I have Perl send the password to a program that prompts for a password

turumkhan has asked for the wisdom of the Perl Monks concerning the following question:

I have to run a command in my perl script by using the back ticks. when i execute that command it asks me for password. Now i wanna pass that password without typing it. for clear understanding of the problem here it goes:

`run the command line`;

now it asks me for password. What i want to do is capture is prompt and pass the password in the script itself rather then typing it all the times. So how do i caputre when the output when it prompts me for the password.

Instead of using backtick, try using either system or opening the command as a pipe. Both of those should allow for greater control than backtick.	[reply]
