Hello *nix friends,
I've written a shell script that allow web admin's to copy file/folder from a development site to the production site. It's more or less a poor man SVN.
I'm posting the script here because I was able to get many questions answered through this forum and also, I want to improve this script. It works as is but there is probably more efficiencies that could be incorporated. Finally, I've keep the comments down for brevity.
If you are working from a local server and need to copy files to a remote server, you could switch out the 'cp' statements with 'scp' statements.
Okay, any thoughts and/or improvements are welcomed.

I would add some error checking. Ensuring that your mkdir was successful when creating your backup directory, and that your backups were created successfully are important. If you care enough to create a backup, you should care enough to make sure that there wasn't a reported error. If you are paranoid, you could md5sum the current file, and md5sum the backup; even if cp reports OK, I have seen cases where the new copy wasn't good.
Another thing that you might need to consider is if any of the files being installed are binaries you will probably have to deal with "text file busy" conditions. Easiest way is to move the destination file away, and then copy the new file in.

UNIX not being a system where mandatory locking's been very popular, I haven't seen this message and don't know what circumstances it'd appear. Can you tell me more?
