-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, 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... 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
--match-length and --dictionary-size options directly to achieve
optimal performance. For example, -9m64 usually compresses executables
more (and faster) than -9.
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.
