the .shrc file runs the commands from the current directory so that would be from the home directory and your file is in the same directory so what you should do instead be call the file like this:

get

or

get.lua

or for example if you would want to run a file from another directory (for example the lib directory) it would look like this:

../lib/get

or

../lib/get.lua

hope this helped
