Ubuntu
coreutils package

Does the dd command run from Ubuntu 11.10 Live CD touch a hard drive in a way that would change environment variables?

Asked by Kent Neilson

I used the Live CD to boot and duplicate a hard disk using the dd command.
Duplication command: sudo dd if=/dev/sda of=/dev/sdb bs=512k
After duplication the original drives environment variables had changed? Can the Live CD do this?

Thank you,

Kent

dd performs low-level copying of raw data. It will not change the environment variables.

I am curious as to what environment variables changed. Where these nix environment or windows environment?

These were nix environment variables.
