or: cp [-arPLHpfinlsu] SOURCE... { -t DIRECTORY | DIRECTORY }
Copy SOURCEs to DEST
-a Same as -dpR
-R,-r Recurse
-d,-P Preserve symlinks (default if -R)
-L Follow all symlinks
-H Follow symlinks on command line
-p Preserve file attributes if possible
-f Overwrite
-i Prompt before overwrite
-n Don't overwrite
-l,-s Create (sym)links
-T Refuse to copy if DEST is a directory
-t DIR Copy all SOURCEs into DIR
-u Copy only newer files
