NAME

       lunzip - decompressor for the lzip format

SYNOPSIS

       lunzip [options] [files]

DESCRIPTION

       Lunzip  is  a  decompressor for the lzip format written in C. Its small size makes it well
       suited for embedded devices or software installers that need to decompress files but don't
       need compression capabilities. Lunzip is fully compatible with lzip 1.4 or newer.

       Lunzip  provides a 'low memory' mode able to decompress any file using as little memory as
       50 kB, irrespective of the dictionary size used to compress  the  file.  To  activate  it,
       specify  the  size  of the output buffer with the option --buffer-size and lunzip will use
       the decompressed file as dictionary for distances beyond the buffer size. Of  course,  the
       larger  the  difference between the buffer size and the dictionary size, the more accesses
       to disk are needed and the slower the decompression is.  This 'low memory' mode only works
       when  decompressing  to  a  regular file and is intended for systems without enough memory
       (RAM + swap) to keep the whole dictionary at once.

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

       -c, --stdout
              write to standard output, keep input files

       -d, --decompress
              decompress (this is the default)

       -f, --force
              overwrite existing output files

       -k, --keep
              keep (don't delete) input files

       -l, --list
              print (un)compressed file sizes

       -o, --output=<file>
              write to <file>, keep input files

       -q, --quiet
              suppress all messages

       -t, --test
              test compressed file integrity

       -u, --buffer-size=<bytes>
              set output buffer size in bytes

       -v, --verbose
              be verbose (a 2nd -v gives more)

       --loose-trailing
              allow trailing data seeming corrupt header

       If no file names are given, or if a file is '-', lunzip 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...  Buffer sizes 12 to 29
       are interpreted as powers of two, meaning 2^12 to 2^29 bytes.

       To  extract all the files from archive 'foo.tar.lz', use the commands 'tar -xf foo.tar.lz'
       or 'lunzip -cd foo.tar.lz | tar -xf -'.

       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 (e.g., bug) which caused lunzip to panic.

       The ideas embodied in lunzip are due to (at least) the following  people:  Abraham  Lempel
       and Jacob Ziv (for the LZ algorithm), Andrey Markov (for the definition of Markov chains),
       G.N.N. Martin (for the definition of range encoding), Igor Pavlov  (for  putting  all  the
       above together in LZMA), and Julian Seward (for bzip2's CLI).
