It was improved in way of maximum +increasing of compression ratio, keeping high decompression speed and +low memory requirements for decompressing. +.PP +.B lzma +command line tool has a similar interface to +.BR gzip (1) +and +.BR bzip2 (1) +and is intended to make use of LZMA compression easy for the users who +are already familiar with gzip and bzip2. +.PP +In this manual +.B lzma +is compared mostly to bzip2 because that is currently one of the most +widely used free software to compress tar files made for distribution. +Comparing lzma to gzip is not practical because neither lzma nor bzip2 +can compete with gzip in compression speed. On the other hand the +compression ratio of gzip is worse than of lzma and bzip2. +.PP +.B lzma +provides notably better compression ratio than bzip2 especially with +files having other than plain text content. The other advantage of +.B lzma +is fast decompression which is many times quicker than bzip2. The major +disadvantage is that achieving the highest compression ratios requires +extensive amount of system resources, both CPU time and RAM. Also +software to handle LZMA compressed files is not installed by default on +most distributions. +.PP +When compressing or decompressing with +.BR lzma , +the new file will have the same ownership information, permissions and +timestamps as the original file. However the this information is not +stored into the compressed file like gzip does. + +.SH STREAMED VS. NON-STREAMED +LZMA files can be either streamed or non-streamed. Non-streamed files +are created only when the size of the file being compressed is known. In +practice this means that the source file must be a regular file. In +other words, if compressing from the standard input or from a named pipe +(fifo) the compressed file will always be streamed. +.PP +Both streamed and non-streamed files are compressed identically; the +only differences are found from the beginnings and ends of LZMA +compressed files: Non-streamed files contain the uncompressed size of +the file in the LZMA file header; streamed files have uncompressed size +marked as unknown. To know where to stop decoding, streamed files have a +special End Of Stream marker at the end of the LZMA file. The EOS marker +makes streamed files five or six bytes bigger than non-streamed. +.PP +So in practice creating non-streamed files has two advantages: 1) the +compressed file is a few bytes smaller and 2) the uncompressed size of +the file can be checked without decompressing the file. To view the data +stored in the LZMA header use +.BR lzmainfo (1). + +.SH OPTIONS +Short options can be grouped like +.BR \-cd. +.TP +.B \-c \-\-stdout \-\-to\-stdout +The output is written to the standard output. The original files are kept +unchanged. When compressing to the standard output there can be only one +input file.

This the default +when called as +.B unlzma +or +.BR lzcat . +.TP +.B \-f \-\-force +Force compression or decompression even if source file is a symlink, +target exists, or target is a terminal. In contrast to gzip and bzip2, +if input data is not in LZMA format, \-\-force does not make lzma +behave like +.BR cat . +.B lzma +never prompts if target file should be overwritten; existing files are +skipped or, in case of +.BR \-\-force , +overwritten. +.TP +.B \-h \-\-help +Show a summary of supported options and quit. +.TP +.B \-k \-\-keep +Do not delete the input files after compression or decompression. +.TP +.B \-L \-\-license +Show licensing information of +.BR lzma . +.TP +.B \-q \-\-quiet +Suppress all warnings. You can still check the exit status to detect if +a warning had been shown. +.TP +.BI "\-S \-\-suffix " .suf +Use +.I .suf +instead of the default +.BR .lzma . +A null suffix forces unlzma to decompress all the given files +regardless of the filename suffix. +.TP +.B \-t \-\-test +Check the integrity of the compressed file(s).

The first two +.RB ( \-1 " and " \-2 ) +are designed for fast compression speed. +.BR \-3 " .. " \-9 +provide good to excellent compression ratio but require more CPU time +and system memory. +.PP +For relatively fast compression with medium compression ratio +.B \-1 +is the recommended setting. It's faster than 'bzip2 \-\-fast' and +usually creates smaller files than 'bzip2 \-\-best'. +.B \-2 +makes somewhat smaller files but doubles the compression time close to +what 'bzip2 \-\-best' takes. +.PP +Generally for excellent compression ratio, acceptable compression time +and memory requirements (about 83 MB for compression, 9 MB for +decompression) you should use +.B \-7 +which is also the default. +.B \-8 +and +.B \-9 +will give some gain especially with bigger files (>=tens of megabytes) +but also increase the CPU and memory requirements dramatically.
