lunzip - decompressor for the lzip format
lunzip [options] [files]
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.
-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.
