This is a very stupid question, but how do I move the contents of a folder to another folder in Linux? I don't want to move the folder itself, just the stuff in it.

In shell (SSH) enter this:
cd old_folder_name
mv * /path/to/other/folder

You can also move specific files such as *.php or *.html (use mv *.php ...)

Thanks, that worked great. My next question: I need to search a folder and all it's subdirectories and delete a file called bob.htm in all of them. How would I do this?
