Shell script needed to modify a file

Hi , I have a list of hosts with IP address and I need a script to ssh into each of the IPs, add the following text into /etc/dhcpcd.conf file.

#Add to /etc/dhcpcd.conf

interface eth0 static ip_address=192.168.1.x/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1

can somehomw advise who to use for loop to do this? I don't have key pair so I am ok with typing in password for 30 times.

the list of IPs i have is from 192.168.1.1 to 192.168.1.30

Thank you!

To write your script, likely better to hire someone to do this, so they can produce a solid script for you.

To resolve the password inputting problem is simple. You'll install the sshpass package on your Linux Distro, so on Debian/Ubuntu...

apt-get install sshpass

Open in new window

Then instead of a key pair, use a command like this...

sshpass -p $password ssh $user@$host -- /path-to-script-here

Open in new window

Keep in mind, if you can login with a password, creating an empty phase phrase key pair is trivial, so better to do this, than use sshpass.
