olaDMXctl

Command-line tool for controlling individual dmx channels with olad

installation

php and curl

This tool is coded in php and uses curl for http-requests so you need to have that installed

# apt update
# apt install php curl

download

Download the script from git.tjdev.de

$ wget -O oladmxctl https://git.tjdev.de/attachments/fc075f16-2923-4856-a4bf-621c5162bee4

Make it executable

$ chmod +x oladmxctl

move into /usr/bin (optional)

You can skip this step. This will only make it so you can call the script from everywhere using oladmxctl. If you skip this step you will have to use ./oladmxctl or /path/to/oladmxctl to run the script.

# mv oladmxctl /usr/local/bin
