Bash scripting is fun and can help you automate a lot of things on your linux servers.

There are a lot of ways to run the same command on multiple servers. You can use pssh for example, bash scripts, python scripts, automation tools etc.

Here’s a simple bash script I wrote to execute the same command on multiple servers from a list. The list should contain one entry per line, either the server ip or hostname.

Create a file, name it server_list and add like 2 servers in that list.

Then download the bash script from my public GitHub repository:

The script has some info at the begging so you can get used with the syntax, also prints help if no arguments are supplied.

If you want to run a command and pipe some arguments to it:
