Just a copy of a big dir when you wan't things like ownership and date etc etc to be untouched. Note: Updated with the ideas from "mpb".

What Others Think

Points for piping and grouping, but this seems like a useless use of tar here. tar provides a 'p' option which is exactly what you what but aren't using. Or you could just use the archive option of cp: cp -a dir_to_cp path_to_put

I prefer the following: tar cf - $source_dir | (cd $dest_dir && tar -xvf -) because: a) It's good practice to use the "&&". If there was something wrong with the "cd" then no data is copied. b) using the "v" on the right hand side shows the file/dir names as they "arrive" at the destination. Again, if something fails, you will see what file/dir was last written OK. Point of historical interest: I often speculate if the "-)" in this tar pipeline was the origin of the smiley. D'ya think? :-)
