How to give input to a pvcs command automatically?

`vget <program name>` is a PVCS command which gets the program to our home directory. This command is given inside a perl program.

This command needs some input to be given.
Eg. Would you like to display milestone label (Y/N)?

We need to respond to this to get the program. Is there any way that i can give input to this automatically..? say N every time?.

So this is an external command that you are executing inside of your Perl script using back tics. Ok, so if you want to feed it a variable or whatever you need to. Since you have the commands documentation, you need to look to see what it supports for input.

Real generic example:

qx is the same as backticks

`vget <program name>` is a PVCS command which gets the program to our home directory. This command is given inside a perl program.

When this command is executed it needs an input to be given in the middle. We need to respond to the below question asked when the command is executed.
Would you like to display milestone label (Y/N)?

Only after we respond to this question the command will execute further. Is there any way that i can give input to this automatically..? say N every time?.

You may give input to the question in the command prompt, even though the question may not get displayed.
But, if you want to set the reply automatically, you may make use of IPC::Run3 module.
