Open tarball

[HelpPleas]

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.

Don't know about Knoppix but it is installed in Ubuntu. Maybe it just needs to be installed:

apt-get install lzma

Then try.

Thanks for your suggestion, but I got this reply:

E: Couldn't find package lzma

Nabble - Gnu - ddrescue - Version 1.11 of GNU ddrescue released

You need the program lzip to extract this. I don't know what version of Debian Knoppix is based on, but it is in the Debian Squeeze repos.
Debian -- Details of package lzip in squeeze

Otherwise you can build it from source.

Or, of course, ddrescue is distributed in other compression formats that will be supported out of the box on knoppix.

OK, I found a gz version which I hadn't previously seen, for some reason.

Thanks very much for your help

Interesting. Since I don't have Knoppix I was going from this page. Under Knoppix the same package is lzip? or are they two different apps?

[reed9]

Apparently, lzip is based on lzma, but not lzma. I thought initially they were the same, but I downloaded the file in question and couldn't extract it using p7zip or any other utility I already had installed.

A little looking and I found lzip on the Arch AUR, and that worked, so I checked the Debian packages (since Knoppix is based on Debian) and found lzip there as well.

Thanks reed9. A just found this which sheds a little more light. I wasn't familiar with either.
