Introduction

onedansh is a CLI utility built in Deno that allows you to instantly create an HTTP endpoint that runs a bash command on your server. It's great for running one-off commands without having to SSH into your server. I personally use it to run pm2 status to check the status of my long running processes. onedansh supports basic token authentication and can return output in JSON or raw text format.

Here's the output of onedansh --help:

Usage: onedansh [OPTIONS] [COMMAND]
Options:
  -h, --help     Show this message
  -v, --version  Show version
  -r, --raw      Return raw output (returns JSON by default)
  --token        Set authentication token
  --port         Set port (default 8080)
  --startup      Run command on startup

Installation

You can run the script with Deno directly:

deno run --allow-net --allow-run https://raw.githubusercontent.com/Nexuist/onedansh/main/onedansh.ts "echo Hello World"

Alternatively, you can build executables for any supported platform with build.sh. You'll need to have Deno installed.

Authentication

If the --token flag is provided, the token will be required to be passed in the Authorization header of the request. Here's an example curl if the token is "abc":

curl -H "Authorization: Bearer abc" localhost:8080

Building

Just run build.sh to build fresh binaries for all supported platforms. You'll need to have Deno installed.

Next Steps

I'm open to adding additional flags if anyone uses this tool and wants a bit more functionality.
It might be nice to allow the requester to specify what format they want the response in (TXT or JSON).
