Programming :: Automate The Password Prompt Required For Sudo Commands?

I have written a script to run commands on remote servers, it is working fine. But when I am running "sudo commands" on the remote servers, it asks for me password after prompting for ssh password. I am unable to automate this password prompt (which is just after ssh password prompt). This is the function I am using to provide passwords

Code:

pass ()
{
cd $DIR/"$dt1"_"$dt"
/usr/bin/perl << 'EOF'
use strict;

[code]....

I want the same function to be used , when it expects for sudo passwords for any of the below lines:

Code:

[sudo] password for vikas: orPassword: This is my "cmd" file passed in pass () function.

Code:

ssh -t -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no 192.168.1.100 "bash rcmds"

This is my script output

Quote:

[vikas@box1 ~]$ ./rscript.sh
++ rm -rf /home/vikas/May_31
++ mkdir -p /home/vikas/May_31
++ set +x

[code]....
