I was trying to uncompress a tar.lz file.

What can I do?

I use lzip, which I compiled from source code, however it can also be installed with Homebrew:

brew install lzip

See also: Lzip

You also need to have Command Line Tools for Xcode installed in either case. Have a look at: How to Install Command Line Tools in OS X Mavericks & Yosemite (Without Xcode)

$ lzip --help
Lzip - LZMA lossless data compressor.

Usage: lzip [options] [files]

Options:
  -h, --help                     display this help and exit
  -V, --version                  output version information and exit
  -a, --trailing-error           exit with error status if trailing data
  -b, --member-size=<bytes>      set member size limit in bytes
  -c, --stdout                   write to standard output, keep input files
  -d, --decompress               decompress
  -f, --force                    overwrite existing output files
  -F, --recompress               force re-compression of compressed files
  -k, --keep                     keep (don't delete) input files
  -l, --list                     print (un)compressed file sizes
  -m, --match-length=<bytes>     set match length limit in bytes [36]
  -o, --output=<file>            if reading standard input, write to <file>
  -q, --quiet                    suppress all messages
  -s, --dictionary-size=<bytes>  set dictionary size limit in bytes [8 MiB]
  -S, --volume-size=<bytes>      set volume size limit in bytes
  -t, --test                     test compressed file integrity
  -v, --verbose                  be verbose (a 2nd -v gives more)
  -0 .. -9                       set compression level [default 6]
      --fast                     alias for -0
      --best                     alias for -9
If no file names are given, or if a file is '-', lzip compresses or
decompresses from standard input to standard output.
Numbers may be followed by a multiplier: k = kB = 10^3 = 1000,
Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
Dictionary sizes 12 to 29 are interpreted as powers of two, meaning 2^12
to 2^29 bytes.

The bidimensional parameter space of LZMA can't be mapped to a linear
scale optimal for all files. If your files are large, very repetitive,
etc, you may need to use the --dictionary-size and --match-length
options directly to achieve optimal performance.

Exit status: 0 for a normal exit, 1 for environmental problems (file
not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
invalid input file, 3 for an internal consistency error (eg, bug) which
caused lzip to panic.

    This worked for me. It pays to note that you'll need to run lzip with the -d (decompress) flag: lzip -d filename.lz – Matt Scheurich Feb 1 '18 at 16:49

$ tar zxvf /usr/local/Sources/lzip-1.19.tar.gz -C /usr/local/Sources/
$ cd /usr/local/Sources/lzip-1.19
$ ./configure --prefix=/usr/local/Custom/lzip
$ make
$ sudo make install

To run lzip

$ /usr/local/Custom/lzip/bin/lzip

http://www.nongnu.org/lzip/lunzip.html

$ tar zxvf /usr/local/Sources/lunzip-1.9.tar.gz -C /usr/local/Sources/
$ cd /usr/local/Sources/lunzip-1.9
$ ./configure --prefix=/usr/local/Custom/lunzip
$ make
$ sudo make install

To run lunzip

$ /usr/local/Custom/lunzip/bin/lunzip 

Now I go to uncompress...

$ /usr/local/Custom/lunzip/bin/lunzip /usr/local/Sources/ddrescue-1.22.tar.lz
$ tar xvf /usr/local/Sources/ddrescue-1.22.tar -C /usr/local/Sources/

Sorry I prefer install in my custom folder!

  • Since I had already posted the answer to your question, I fail to see the need for what you posted as an answer. – user3439894 Oct 4 '17 at 21:35
  • Unfortunately, When I do my steps and solve my question, I see later your answer. I don't want to use Homebrew. – Chepe Questn Oct 4 '17 at 22:38
  • You don't have to use Homebrew, I only included it in case you couldn't compile it from source code as I did! – user3439894 Oct 4 '17 at 22:40
