I downloaded this file: ddrescue-1.11.tar.lz

I found I was unable to open it, I tried tar with various parameters.

I also tried this:
lzcat ddrescue-1.11.tar.lz | tar x
I got the reply:
bash: lzcat: command not found

Has anyone got a suggestion?
If you could point me to help on opening all kinds of tarball, I would be grateful.
