Description Lunzip is a decompressor for lzip files. 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 do not need compression capabilities. Lunzip uses the same well-defined exit status values used by lzip and bzip2, which makes it safer when used in pipes or scripts than decompressors returning ambiguous warning values, like gunzip. The 4 factor integrity checking of the lzip format guarantees that the decompressed version of the data is identical to the original. This guards against corruption of the compressed data, and against undetected bugs in lunzip (hopefully very unlikely). The chances of data corruption going undetected are microscopic. Be aware, though, that the check occurs upon decompression, so it can only tell you that something is wrong. It can't help you recover the original uncompressed data. If you ever need to recover data from a damaged lzip file, try the lziprecover program. Lziprecover makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving. Lunzip replaces every file given in the command line with a decompressed version of itself. Each decompressed file has the same modification date, permissions, and, when possible, ownership as the corresponding compressed file. Lunzip is able to read from some types of non regular files if the "--stdout" option is specified. Lunzip attempts to guess the name for the decompressed file from that of the compressed file as follows: filename.lz becomes filename filename.tlz becomes filename.tar anyothername becomes anyothername.out If no file names are specified, lunzip decompresses from standard input to standard output. In this case, lunzip will decline to read compressed input from a terminal. Lunzip will correctly decompress a file which is the concatenation of two or more compressed files. The result is the concatenation of the corresponding uncompressed files. Integrity testing of concatenated compressed files is also supported. The amount of memory required by lunzip to decompress a file is only a few tens of KiB larger than the dictionary size used to compress that file.
