ethercat command not found after full installtion

I have been trying for the past few days to get the ethercat working with Linuxcnc but my lack of knowledge about the Linux environment does not allow me to even start the project. I have all the necessary hardware and have the Debian 10 version with rt kernel and linux cnc preinstalled and I did all the installation procedure according to this link: forum.linuxcnc.org/10-advanced-configura...at-on-raspberry-pi-4 The installation completes with no errors but I get a after i reboot and try to runI would appreciate if anyone could help

thank you for your reply,
Could you please provide me a link on how to install the drivers and also how to config the ini, xml, and hal files for the Ek1100 and a AKD driver?
i greatly appreciate your guidance.

The driver has two parts . the master and what connects to HAL
You can find the master here : gitlab.com/etherlab.org/ethercat
The component that links it to HAL can be found here : github.com/sittner/linuxcnc-ethercat (This also has some good examples )
But installing them directly is a bit of a workout, so you might want to check this out :
