copy/mkdir and automatically create parent directories
The --parents option will cause cp or mkdir to automatically create the parent directory structure. $mkdir --parents /one/two/three/dir will create /one, /one/two, and /one/two/three as needed before creating dir. cp will copy files with their full directory structure into the target directory with this option. Thanks to Peter Leung at: http://linuxcommando.blogspot.com/2007/11/use-of-parents-flag-in-mkdir-and-c.html which has good examples of usage.
