repsh

repsh is a command-line utility designed for executing commands on remote machines. It facilitates the distribution and execution of single commands or scripts across a fleet of servers efficiently. The tool typically operates by establishing SSH connections to the target hosts and then running the specified command. repsh aims to simplify the process of managing multiple servers, allowing administrators to perform repetitive tasks, deploy updates, or gather information from numerous systems simultaneously without requiring manual intervention on each machine.

The core functionality of repsh revolves around its ability to take a list of target hosts and a command as input. It then connects to each host via SSH, often utilizing pre-configured SSH keys for passwordless authentication. Once connected, the command is executed on the remote system, and its output is collected and presented to the user. This aggregation of results makes it easy to monitor the status of operations across the entire fleet. repsh can be particularly useful for tasks like checking service status, restarting daemons, or running diagnostic scripts. Its design emphasizes speed and simplicity for executing ad-hoc commands on a distributed infrastructure.
