pcmd

pcmd is a Go program that executes commands defined in a YAML file concurrently, with colorful output for each command.

This program was made to simplify the process of running multiple long-running commands concurrently, while still being able to distinguish between the output of each command.

Installation

Install pcmd either through the GitHub releases page or by building from source.

GitHub Releases

Download the latest release from the GitHub releases page and extract the binary for your system.

Go Install

1. Run go install github.com/fieu/pcmd@latest
2. The binary will be installed to $GOPATH/bin (e.g. ~/go/bin)

Building from Source

Prerequisites

• Go 1.16 or later
• GNU Make

1. Clone the repository using git clone https://github.com/fieu/pcmd.git
2. Build the binary using make build
3. Move the compiled binary to a directory in your PATH (e.g. /usr/local/bin)
4. Make the binary executable using chmod +x pcmd

Usage

To use pcmd, create a YAML file (pcmd.yml) with the following structure:

- name: System Log
  command: tail -f /var/log/system.log
- name: WiFi
  command: tail -f /var/log/wifi.log

Each command consists of a name and a command field. Customize the commands as per your requirements.

Once you have the YAML file set up, run pcmd using the following command in the same directory as the YAML file:

pcmd

pcmd will read the YAML file, execute the commands concurrently, and display the output with colorful prefixes for each command.

Both stdout and stderr are displayed in the output. If a program exits, pcmd will display the exit code.
