Bash Scripted Linux Automated File Transfer Script

I have content present on several different linux servers. I would like to organize and schedule replacements of the content from a central (home) [login to view URL] home server will have a always-changing [login to view URL] content is in the same directory on all servers but I do not have the same content on all servers at the same time. The content can only be replaced at a certain time of the [login to view URL] is,however,a cronjob script I wrote running on the servers that: 1) checks for a certain file's contents-it's a 0,nothing happens and the script terminates,if it's a 1,it continues; 2) Run a script that 'pre-processes' the new files I have uploaded that day. 3) Removes the old content directory 4) mv's the new content dir. into the old dir. name 5) Change the flag of the file back to 0 This eases things a bit and enables me to upload the new content to each server during the day and then 'hands off' that night the server will update with the new [login to view URL],this setup requires me to upload the replacement content the day before the update,and do it for EACH [login to view URL] a result,I would like a way to prep and schedule the new content set(s) on the central server and then know that on Date X content will automatically upload and then update on the remote servers without requiring my presence. So as an example: April 23; Replace the remote content directory on: Servers 1,3,5 with localdir X Server 2 with localdir Y Server 4 with localdir Z. Ideally a php/mysql driven interface would exist to control scheduling of the updates,as well to keep track and log the history of what content was on what server. The method should stray from the remote servers making any requests to the home one. I have passwordless key-based ssh logins set up to all servers, facilitating a solution with rcopy/rsh commands through a bash [login to view URL] me this would be the ideal situation. The process needs to be logging and error-checking with error recovery. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
