Honestly: i don't know. You gave a roundabout description of your requirement and i wrote a roundabout solution. To really implement this you will need to specify in much more detail what your requirement is.
For instance (one of the things needing clarification): what should happen after taking the server offfline? Wait for some time and put it online again? (If yes: how long would be "some time"?) Do nothing and leave it offline?
Another detail needing clarification: what is meant by "send file(s)"? Transfer it with scp/rcp/rsync/ftp/sftp/or the likes? Socket communication? Anything else?
In any case: what i wrote was pseudo-code, which just shows a possible logic and control flow of a program which has to be implemented. To actually implement it you need to select a programming language first which you want to use (i.e. "bash" or "Korn Shell" or "perl" or "ruby" or "python" or "whatever else you might want to use, version 3.141596", etc..
I hope this helps.
