Copy a Directory from Command Line
Copying a directory for the sake of backup is something I do often, especially when I'm trying to figure out why something isn't working when I use an external library. I'll copy the directory structure as a backup, mess around with the original source until I find a solution, then restore the original and change my overall system code to bring in my revised version.
You can't just use cp to copy a directory structure -- you'll see cp: myDir is a directory (not copied). You'll need to add a few additional flags to copy a directory structure:
cp -Rp source source_copy
The above command copies the directory recursively while keeping the same permissions!

One major problem with creating UI components with the MooTools JavaScript framework is that there isn't a great way of allowing customization of template and ease of node creation. As of today, there are two ways of creating:

Remember the old days of DHTML and effects that were an achievement to create but had absolutely no value? Well, a trailing mouse cursor script is sorta like that. And I'm sorta the type of guy that creates effects just because I can.

Why do you have the
-sflag in there? Looking at the--helpforcp, that’s the option to “make symbolic links instead of copying”, and according to Stack Overflow http://stackoverflow.com/questions/1240636 , that doesn’t even work recursively (with the-Rflag). (Nor can I see why you would want to copy an entire directory recursively only for it to be populated with symlinks, especially “for the sake of backup”.) Typo?EDIT: David has since corrected the error in question.
Another great option that I somehow always forget to use is -a (archive), used like so:
It copies structure and permissions and also preserves symlinks.
Just use rsync, faster and more options. )
Good to know. But I agree with @John
I prefer to use rsync for this purpose
