What's the difference between dd and cat > ?
So I went to VMWare training this week and one of the processes for P2V conversion involves booting to a Linux live CD on the physical server and executing:
cat /dev/[Pdisk1] > //[NFS server]:/[share]/[temp]
and then booting to the Linux CD on the VM and executing:
cat //[NFS server]:/[share]/[temp] > /dev/[Vdisk1]
I never knew you could use cat and redirection to clone a device, so my question is what's the difference between cat > and dd?
