41
42 -l, --list

59
60 -t, --test
61 test compressed file integrity
62
63 -v, --verbose
64 be verbose (a 2nd -v gives more)
65
66 -0 .. -9
67 set compression level [default 6]
68
69 --fast alias for -0
70
71 --best alias for -9
72
73 --loose-trailing
74 allow trailing data seeming corrupt header
75
76 If no file names are given, or if a file is '-', lzip compresses or
77 decompresses from standard input to standard output. Numbers may be
78 followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024,
79 M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc... Dictionary sizes 12
80 to 29 are interpreted as powers of two, meaning 2^12 to 2^29 bytes.
81
82 The bidimensional parameter space of LZMA can't be mapped to a linear
83 scale optimal for all files. If your files are large, very repetitive,
84 etc, you may need to use the --dictionary-size and --match-length
85 options directly to achieve optimal performance.
86
87 Exit status: 0 for a normal exit, 1 for environmental problems (file
88 not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
89 invalid input file, 3 for an internal consistency error (eg, bug) which
90 caused lzip to panic.
