Command Runner

Working on a basic command runner to run SSH commands to multiple devices.

Currently working with netmiko. Pulls list of hostnames or IPs from src/input/devices.txt and runs commands against them.

Getting started

Requirements

Python 3.10 (Uses newer typing features)
netmiko
rich

Basic install

git clone https://github.com/DavidTWynn/command_runner.git
cd command_runner
python3.10 -m pip install -r requirements.txt

Config

src/input/devices.txt
src/input/commands.txt

Create a devices.txt file in the input directory based off of the devices_example.txt file. These devices will be logged into via ssh and commands will be ran against them.

Can be IPv4 address or hostname

> cat devices.txt
127.0.0.1
127.0.0.2
127.0.0.3
localhost
localhost.localhost

Edit commands.txt with the commands you want sent to each device

> cat commands.txt
show int gi0/0 description
show int gi0/0 | i MTU

Run script

> python3.10 src/command_runner.py
