From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why not DD? Dd is agnostic to anything, just copy over the entire partition and you're golden
Man I always forget about dd and jump to gparted.
dd is good if the destination disk is equal or bigger, unless you are brave enough to shrink the source partition.
if you are moving to a smaller disk for whatever reason (hdd to sdd) then you need to fallback to a different method, which takes us back to cp/rsync.
I'm always hesitant to use the "disk destroyer", even as a regular user.
rsyncdoes a good job and it's maybe even more agnostic thanddsince it doesn't really care about the partition size, as long as all data fits.Because
catandcpare faster if you don't pick a good block size fordd.How are you supposed to use
catto copy files?catting binary files does, interesting things.You cat the device files of the partitions directly into each other.
cat /dev/sda/ > /dev/sdb?
