LZF(1)                      General Commands Manual                     LZF(1)

NAME
     lzf -- compress and uncompress files using LZF algorithm

SYNOPSIS
     lzf [-bcdfhv] file [file [...]]
     unlzf file [file [...]]
     lzfcat file [file [...]]

DESCRIPTION
     lzf is a simple program to compress or uncompress files using LZF
     (sometimes known as "Lempel-Ziv Fast") coding.  LZF is extremely fast,
     about 75% of the performance of memcpy(3) for many inputs, while offering
     a moderate compression ratio, usually between 1.5:1 and 2:1.

     When compressing, it removes each input file and replaces it with an
     output file with the suffix ``.lzf'' appended.  When uncompressing, it
     removes each input file and replaces it with an output file with the
     suffix ``.lzf'' removed.  If no files are specified as arguments,
     standard input and standard output are used as input and output
     respectively.

     If invoked as lzf, the default mode of operation is to compress.  If
     invoked as unlzf, the default mode of operation is to uncompress.  If
     invoked as lzfcat, the default mode of operation is to uncompress to
     standard output.

OPTIONS
     The following options are available:

     -b     This option selects a compression blocksize.  Small compression
            block sizes give poor compression and slow operation; the default
            of 64KiB is strongly recommended.  Block sizes larger than 64KiB
            are silently reduced to 64KiB in order to not produce output
            incompatible with other versions of lzf.

     -c     This option selects compression.

     -d     This option selects decompression.

     -f     This option forces overwrite of preexisting output files, if any.

     -h     This option prints command usage.

     -v     This option prints compression statistics for each file processed.

HISTORY
     The lzf program was first included with version 0.1 of Marc Lehmann's LZF
     library.  It was rewritten for version 2.0 of the library to offer the
     current syntax, which is mostly compatible with other compression
     utilities such as gzip(1).  The lzf program first appeared in NetBSD 7.0.

AUTHORS
     The lzf program was written by Stefan Traby <stefan@hello-penguin.com>.

BUGS
     Some versions of lzf install a program named ``lzcat'' instead of lzfcat.
     Because the (lzcat) name is also used by xz(1), in NetBSD the name lzfcat
     is used instead.
