Running Lua script on OpenWRT directly (without running lua first)

On OpenWRT, I have a Lua script on_new_device.lua that runs fine if I execute lua on_new_device.lua; however, I'd like to run it simply by executing ./on_new_device.lua.

Executing ./on_new_device.lua returns this error...

root@router:~# ./on_new_device.lua
-ash: ./on_new_device.lua: not found

The file has execute permissions...

root@router:~# ls -la ./on_new_device.lua
-rwxrwxrwx    1 root     root          1094 Jun 18 11:06 ./on_new_device.lua

The file starts with #!/usr/bin/lua...

root@router:~# head -1 ./on_new_device.lua
#!/usr/bin/lua

How can I execute this file directly?

Can you wrap it in a script?

Copy this into a test.ash file:

#!/bin/ash

/usr/bin/lua /[path]/on_new_device.lua

Then chmod 755 on test.ash, and then you can run:

./test.ash

Bah, the problem was that the lua script was created on a Windows machine and had \r\n line endings. Saving the file with \n line endings solved the issue.
