Script for changing the password

[Koul, Minoti]

Hi Managers,
I am in a situation wherein I have to change root password of 100 odd
unix boxes. I wanted to do the same via a script.

I used to do it the crude way
#!/bin/ksh -x
cp -p /etc/shadow /etc/shadow.11
cat /etc/shadow|grep -v root>/tmp/shad1
echo "root:O75xmUttfitCw:12794::::::">>/tmp/shad2 ## here I am echoing
the encripted string for new password"
cat /tmp/shad1>>/tmp/shad2
cp /tmp/shad2 /etc/shadow
/usr/sbin/pwconv
chown root:sys /etc/shadow
chmod 400  /etc/shadow

I understand that we can input the new password via a script using !! .
But have'nt been able to do this successfully.
Can you please help out.
