Hello, Thanks for visiting RvKmR.blogspot.in . In this blog, I am going to explain about my script “Reset multiple Linux server password” written in bash. To understand this script you must be familiar with Bash scripting and Linux environment. Q : I have 100 's Linux server, I need to reset these Linux server password on weekly. I know procedure to reset password of single server i.e. Login in to target server and reset password with utility “passwd”. But here is issue : What if I have 100 's of server ? it is not efficient way to login to each server and the reset password. Ans : Written an bash script to automate this task. Details are mentioned below. There are some prerequisites needed before running this script. We need know targeted Linux server IP address and current password of server. Create a file “server_details” at same location where is your main script located and write IP address and password like : "<IP>:<old_password>"
