@@ -5,6 +5,18 @@ 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 bzip2, +which makes it safer when used in pipes or scripts than compressors +returning ambiguous warning values, like gzip. + +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. |
