script to rm files on multiple servers
Hello All,
New guy to the " dark side " of command line and trying hard to improve/establish a decent bash scripting ability. Have a need for a script sooner than later so I thought I would call out for help. I need to have a bash script that can rm a file from multiple servers if logged onto one. Is there an easy way to do this? I am thinking that I need a variable list of server names to use in the script along with just a simple rm /filepath. Wouldn't I have to somehow " log into" each server to do the remove? Would the script have to include an ssh to each server in the variable list ? Trying to think out loud for this.... Thanks in advance for the help, Steve

Steve,
Welcome to nixCraft forum! Yes a script can be used to run files and all other stuff. First, you need to setup password less login using ssh-keys between your host and other servers: Howto Linux / UNIX setup SSH with DSA public key authentication (password less login) Howto use multiple SSH keys for password less login The host will run a script, it will login to each system and it will remove files. Here is a sample script to kick start development: Code:
#!/bin/bash SERVERS="box1 box2 box3" for b in $SERVERS do ssh user@$b /bin/rm /path/to/file done
