type "man mv" into a terminal and read up.
mv /somefolder/* /anotherfolder/*

There's almost always more than way to do something in Linux. And more importantly, there are almost always caveats. There are more and less percise ways to do things. For example, using cp or cp -r will copy files from one place to another, but can / will still alter those files as far as the file system is concerned. A file is more than its contents after all. There is metadata for that file that is used by the files system, like creation time, access time, owner, permissions, etc. cp will not perserve this information.

You can also look at the cpio and rsync commands, depending on what exactly your needs are.
