dd is a raw copy. In cases like this when you want to shift a full partition, time is secondary. It is a one time job.
A "dd" would do raw copy of of the whole thing inclusive of existing fragmented spaces. When you do dd of stuff like /usr which may be over 1 gig, the target media should be at least of that size if not larger. Secondly dd of all mounted parti- tions should be avoided ... cp -a (or dpR) would copy everything in a logical order with fragmentation minimised and all attributes and permissions perfectly retained. With cp you also have the option of mov- ing different parts of the same partition to two or more seperate partitions (e.g. segregate /usr/local from /usr and mount them seperately through fstab). I would definitely go by what Mithun has also advocated.

Type 'man grep' for details. ####<From : freebsd fortune>################################## : _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
