(The name of pdlzip comes from 'public domain +lzip'). Pdlzip is written in C and is (hope)fully compatible with lzip 1.4 +or newer. .PP +Lzip is a lossless data compressor with a user interface similar to the +one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip \fB\-0\fR) +or compress most files more than bzip2 (lzip \fB\-9\fR). Decompression speed is +intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 +from a data recovery perspective. Lzip has been designed, written and +tested with great care to replace gzip and bzip2 as the standard +general\-purpose compressed format for unix\-like systems. +.PP +Pdlzip is also able to decompress legacy lzma\-alone (.lzma) files. Lzma\-alone is a very bad format; it is essentially a raw LZMA stream. If you keep any lzma\-alone files, it is advisable to recompress them to lzip format. Lziprecover can convert some lzma\-alone files to lzip format @@ -57,11 +69,11 @@ test compressed file integrity \fB\-v\fR, \fB\-\-verbose\fR be verbose (a 2nd \fB\-v\fR gives more) .TP -\fB\-1\fR .. \fB\-9\fR +\fB\-0\fR .. \fB\-9\fR set compression level [default 6] .TP \fB\-\-fast\fR -alias for \fB\-1\fR +alias for \fB\-0\fR .TP \fB\-\-best\fR alias for \fB\-9\fR @@ -91,7 +103,7 @@ Report bugs to lzip\-bug@nongnu.org .br Pdlzip home page: http://www.nongnu.org/lzip/pdlzip.html .SH COPYRIGHT -Copyright \(co 2018 Antonio Diaz Diaz. +Copyright \(co 2019 Antonio Diaz Diaz.
