=head1 NAME
|
||||
|
||||
lrz - gzip compatible command line variant of lrzip
|
||||
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
lrz [OPTIONS] <file>
|
||||
B<lrz> [options] I<file>
|
||||
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
lrz is identical to the lrzip application however its command line options and
|
||||
behaviour are made to be as compatible with gzip as possible.
|
||||
B<lrz> is identical to the B<lrzip> application, however, its command
|
||||
line options and behaviour are made to be as compatible with B<gzip>
|
||||
as possible.
|
||||
|
||||
=head1 OPTIONS
|
||||
|
||||
lrz differs from lrzip by accepting the following commands:
|
||||
=head2 General options
|
||||
|
||||
General options:
|
||||
-c, --stdout output to STDOUT
|
||||
-C, --check check integrity of file written on decompression
|
||||
-d, --decompress decompress
|
||||
-e, --encrypt password protected sha512/aes128 encryption on compression
|
||||
-h, -?, --help show help
|
||||
-H, --hash display md5 hash integrity information
|
||||
-i, --info show compressed file information
|
||||
-L, --license display software version and license
|
||||
-P, --progress show compression progress
|
||||
-r, --recursive operate recursively on directories
|
||||
-t, --test test compressed file integrity
|
||||
-v[vv], --verbose Increase verbosity
|
||||
-V, --version show version
|
||||
Options affecting output:
|
||||
-f, --force force overwrite of any existing files
|
||||
-k, --keep don't delete source files on de/compression
|
||||
-K, --keep-broken keep broken or damaged output files
|
||||
-o, --outfile filename specify the output file name and/or path
|
||||
-O, --outdir directory specify the output directory when -o is not used
|
||||
-S, --suffix suffix specify compressed suffix (default '.lrz')
|
||||
Options affecting compression:
|
||||
-b, --bzip2 bzip2 compression
|
||||
-g, --gzip gzip compression using zlib
|
||||
-l, --lzo lzo compression (ultra fast)
|
||||
-n, --no-compress no backend compression - prepare for other compressor
|
||||
-z, --zpaq zpaq compression (best, extreme compression, extremely slow)
|
||||
Low level options:
|
||||
-1 .. -9 set lzma/bzip2/gzip compression level (1-9, default 7)
|
||||
--fast alias for -1
|
||||
--best alias for -9
|
||||
-L, --level level set lzma/bzip2/gzip compression level (1-9, default 7)
|
||||
-N, --nice-level value Set nice value to value (default 0)
|
||||
-p, --threads value Set processor count to override number of threads
|
||||
-m, --maxram size Set maximim available ram in hundreds of MB
|
||||
overrides detected ammount of available ram
|
||||
-T, --threshold Disable LZO compressibility testing
|
||||
-U, --unlimited Use unlimited window size beyond ramsize (potentially much slower)
|
||||
-w, --window size maximum compression window in hundreds of MB
|
||||
default chosen by heuristic dependent on ram and chosen compression
