I've been having this weird problem with typing commands into gnome-terminal. If the command takes up multiple screen lines and I use any backspaces and the stars are in proper alignment the command becomes garbled but is echoed back fine. I typed and was echoed this:
sudo dd if=debian-6.0.5-amd64-businesscard.iso of=/dev/sdb
however that command returned this:
sudddd: command not found
curiously my history contained this:
sudddd o if=debian-6.0.5-amd64-businesscard.iso of=/=/dev/sdb
These garbled commands almost impersonate my intended command. Really really annoying. Also you may note how dangerous this becomes when using sudo. I don't know if anyone has had similar issues and couldn't find anything while googling.
