How uncompress tar.lz file

tarterminal

I was trying to uncompress a tar.lz file.

xz: Compressed data cannot be written to a terminal
xz: Try `xz --help' for more information.

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.
