Linux lingo.....

I have no idea how to actually set up the deamons. It says create a script but i can only create basic text, it says to make it executable, doesn't work on the basic text(although it doesn't say failed when I do it)
Can someone please explain this step to me assuming I know nothing, which is about the truth. I'm running slackware 9 like the little box says
To start the server as a deamon you should create a script something like this one, perhaps calling it startsmb.
#!/bin/sh
/usr/local/samba/bin/smbd -D
/usr/local/samba/bin/nmbd -D
Then make it executable with chmod +x startsmb
You can then run startsmb by hand or execute it from /ect/rc.local
Thank you so much
