NAME

       lunzip - decompressor for the lzip format

SYNOPSIS

       lunzip [options] [files]

DESCRIPTION

       Lunzip  is a decompressor for the lzip format. It is written in C and 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 '--buffer-size' option and lunzip will  use
       the  decompressed  file as dictionary for distances beyond the buffer size. Of course, the
       smaller the buffer size used in relation to 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>
              if reading standard input, write to <file>

       -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.

       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 lunzip to panic.
