How to read userid and password information from txt file
Hi Experts,

I am writing a shell script (for displaying disk space details) which is logging to 15 different servers using following command.
ssh userid@servername
It is prompting me for password for all 15 servers when I manually run it.
However , soon I would like to schedule this script for daily cron job run.
How I can modify this shell script to read the userid and password information from txt file ?

PS : All my 15 servers are on SunOS.
uname -v
Generic_118558-27

Thanks,
Ajay

search in this forum for "password less ssh"

you need to install your server public keys in all the 15 servers ( for password less connectivity )
