              set match length limit in bytes [36]

       -o, --output=<file>
              if reading standard input, write to <file>

       -q, --quiet
              suppress all messages

LZIP(1)                   User Commands                   LZIP(1)


       -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

       --loose-trailing
              allow trailing data seeming corrupt header

       If no file names are given, or if a file is '-', lzip com-
       presses 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.
