For examples like this:


ubuntu@ubuntu-desktop:~$ cd Downloads

The "ubuntu@ubuntu-desktop:~$" part is just an example prompt. Sometimes it will be just a "$" (or a "#" if the command is being run by the root user, something rare in Ubuntu examples). Your prompt is "k@ubuntu:~$" instead. So just do:


cd Downloads
md5sum your-actual-filename-here

where "your-actual-filename-here" is the actual name of the file you're trying to md5sum.

There should be a list of MD5 checksums at the site you downloaded the CD image from. Compare it to that to see if it is good.

e.g. http://ftp.heanet.ie/pub/ubuntu-cdimage/releases/11.10/release/MD5SUMS

can md5sum tell same or different when iso file is pasted in terminal, and compared with iso file used as installation?
