-    (tested working on Ubuntu server and Debian)
-
--If airmon-ng doesn't work use "ifconfig <inerface> down" then "iwconfig <interface> mode monitor" and finally
-  "ifconfig <interface> up"

-  or from "https://unix.stackexchange.com/questions/3809/how-can-i-make-a-program-executable-from-everywhere"
-  quote "If you just type export PATH=$PATH:</path/to/file> at the command line it will only last for the length of the session.
-  If you want to change it permanently add export PATH=$PATH:</path/to/file> (the bin/ folder) to your ~/.bashrc file (just at the end is fine)."

-  ExecStart="PATHTOEXECUTABLE --OPTIONS"
-
-  [Install]
-  WantedBy=multi-user.target
-  }
-  And then enable it using "systemctl whatever.service enable", here are some guides and references:
