+.br
+.B lzcat

+.PP
+When writing scripts that need to decompress files,
+it is recommended to always use the name
+.B xz
+with appropriate arguments
+.RB ( "xz \-d"
+or
+.BR "xz \-dc" )
+instead of the names
+.B unxz
+and
+.BR xzcat .
+.
+.SH DESCRIPTION
+.B xz
+is a general-purpose data compression tool with
+command line syntax similar to
+.BR gzip (1)
+and
+.BR bzip2 (1).
+The native file format is the
+.B .xz
+format, but the legacy
+.B .lzma
+format used by LZMA Utils and
+raw compressed streams with no container format headers
+are also supported.
+.PP
+.B xz
+compresses or decompresses each
+.I file
+according to the selected operation mode.
+If no
+.I files
+are given or
+.I file
+is
+.BR \- ,
+.B xz
+reads from standard input and writes the processed data
+to standard output.
+.B xz
+will refuse (display an error and skip the
+.IR file )
+to write compressed data to standard output if it is a terminal.
+Similarly,
+.B xz
+will refuse to read compressed data
+from standard input if it is a terminal.
+.PP
+Unless
+.B \-\-stdout
+is specified,
+.I files
+other than
+.B \-
+are written to a new file whose name is derived from the source
+.I file
+name:
+.IP \(bu 3
+When compressing, the suffix of the target file format
+.RB ( .xz
+or
+.BR .lzma )
+is appended to the source filename to get the target filename.
+.IP \(bu 3
+When decompressing, the
+.B .xz
+or
+.B .lzma
+suffix is removed from the filename to get the target filename.
+.B xz
+also recognizes the suffixes
+.B .txz
+and
+.BR .tlz ,
+and replaces them with the
+.B .tar
+suffix.
+.PP
+If the target file already exists, an error is displayed and the
+.I file
+is skipped.
+.PP
+Unless writing to standard output,
+.B xz
+will display a warning and skip the
+.I file
+if any of the following applies:
+.IP \(bu 3
+.I File
+is not a regular file.
+Symbolic links are not followed,
+and thus they are not considered to be regular files.
+.IP \(bu 3
+.I File
+has more than one hard link.
+.IP \(bu 3
+.I File
+has setuid, setgid, or sticky bit set.
+.IP \(bu 3
+The operation mode is set to compress and the
+.I file
+already has a suffix of the target file format
+.RB ( .xz
+or
+.B .txz
+when compressing to the
+.B .xz
+format, and
+.B .lzma
+or
+.B .tlz
+when compressing to the
+.B .lzma
+format).
+.IP \(bu 3
+The operation mode is set to decompress and the
+.I file
+doesn't have a suffix of any of the supported file formats
+.RB ( .xz ,
+.BR .txz ,
+.BR .lzma ,
+or
+.BR .tlz ).
+.PP
+After successfully compressing or decompressing the
+.IR file ,
+.B xz
+copies the owner, group, permissions, access time,
+and modification time from the source
+.I file
+to the target file.
+If copying the group fails, the permissions are modified
+so that the target file doesn't become accessible to users
+who didn't have permission to access the source
+.IR file .
+.B xz
+doesn't support copying other metadata like access control lists
+or extended attributes yet.
+.PP
+Once the target file has been successfully closed, the source
+.I file
+is removed unless
+.B \-\-keep
+was specified.
+The source
+.I file
+is never removed if the output is written to standard output.
+.PP
+Sending
+.B SIGINFO
+or
+.B SIGUSR1
+to the
+.B xz
+process makes it print progress information to standard error.
+This has only limited use since when standard error
+is a terminal, using
+.B \-\-verbose
+will display an automatically updating progress indicator.
+.
+.SS "Memory usage"
+The memory usage of
+.B xz
+varies from a few hundred kilobytes to several gigabytes
+depending on the compression settings.
+The settings used when compressing a file determine
+the memory requirements of the decompressor.
+Typically the decompressor needs 5\ % to 20\ % of
+the amount of memory that the compressor needed when
+creating the file.
+For example, decompressing a file created with
+.B xz \-9
+currently requires 65\ MiB of memory.
+Still, it is possible to have
+.B .xz
+files that require several gigabytes of memory to decompress.
+.PP
+Especially users of older systems may find
+the possibility of very large memory usage annoying.
+To prevent uncomfortable surprises,
+.B xz
+has a built-in memory usage limiter, which is disabled by default.
+While some operating systems provide ways to limit
+the memory usage of processes, relying on it
+wasn't deemed to be flexible enough (e.g. using
+.BR ulimit (1)
+to limit virtual memory tends to cripple
+.BR mmap (2)).
+.PP
+The memory usage limiter can be enabled with
+the command line option \fB\-\-memlimit=\fIlimit\fR.
+Often it is more convenient to enable the limiter
+by default by setting the environment variable
+.BR XZ_DEFAULTS ,
+e.g.\&
+.BR XZ_DEFAULTS=\-\-memlimit=150MiB .
+It is possible to set the limits separately
+for compression and decompression
+by using \fB\-\-memlimit\-compress=\fIlimit\fR and
+\fB\-\-memlimit\-decompress=\fIlimit\fR.
+Using these two options outside
+.B XZ_DEFAULTS
+is rarely useful because a single run of
+.B xz
+cannot do both compression and decompression and
+.BI \-\-memlimit= limit
+(or \fB\-M\fR \fIlimit\fR)
+is shorter to type on the command line.
+.PP
+If the specified memory usage limit is exceeded when decompressing,
+.B xz
+will display an error and decompressing the file will fail.
+If the limit is exceeded when compressing,
+.B xz
+will try to scale the settings down so that the limit
+is no longer exceeded (except when using \fB\-\-format=raw\fR
+or \fB\-\-no\-adjust\fR).
+This way the operation won't fail unless the limit is very small.
+The scaling of the settings is done in steps that don't
+match the compression level presets, e.g. if the limit is
+only slightly less than the amount required for
+.BR "xz \-9" ,
+the settings will be scaled down only a little,
+not all the way down to
+.BR "xz \-8" .
+.
+.SS "Concatenation and padding with .xz files"
+It is possible to concatenate
+.B .xz
+files as is.
+.B xz
+will decompress such files as if they were a single
+.B .xz
+file.
+.PP
+It is possible to insert padding between the concatenated parts
+or after the last part.
+The padding must consist of null bytes and the size
+of the padding must be a multiple of four bytes.
+This can be useful e.g. if the
+.B .xz
+file is stored on a medium that measures file sizes
+in 512-byte blocks.
+.PP
+Concatenation and padding are not allowed with
+.B .lzma
+files or raw streams.
+.
+.SH OPTIONS
+.
+.SS "Integer suffixes and special values"
+In most places where an integer argument is expected,
+an optional suffix is supported to easily indicate large integers.
+There must be no space between the integer and the suffix.

+Multiply the integer by 1,024 (2^10).

+.IP ""
+These BCJ filters are very fast and
+use insignificant amount of memory.
+If a BCJ filter improves compression ratio of a file,
+it can improve decompression speed at the same time.

+the decompression speed of LZMA2 is roughly
+a fixed number of bytes of compressed data per second.

+.RS
+.IP \(bu 3
+Some types of files containing executable code
+(e.g. object files, static libraries, and Linux kernel modules)

+These BCJ filters will still do the address conversion,

+.IP \(bu 3
+Applying a BCJ filter on an archive containing multiple similar
+executables can make the compression ratio worse than not using

+.RE

+.SS "Streamed vs. non-streamed .lzma files"
+The uncompressed size of the file can be stored in the

+LZMA Utils does that when compressing regular files.
+The alternative is to mark that uncompressed size is unknown
+and use end-of-payload marker to indicate
+where the decompressor should stop.
+LZMA Utils uses this method when uncompressed size isn't known,
+which is the case for example in pipes.
+.PP
+.B xz
+supports decompressing
+.B .lzma
+files with or without end-of-payload marker, but all
+.B .lzma
+files created by
+.B xz
+will use end-of-payload marker and have uncompressed size
+marked as unknown in the
+.B .lzma
+header.
+This may be a problem in some uncommon situations.
+For example, a
+.B .lzma
+decompressor in an embedded device might work
+only with files that have known uncompressed size.
+If you hit this problem, you need to use LZMA Utils
+or LZMA SDK to create
+.B .lzma
+files with known uncompressed size.
+.
+.SS "Unsupported .lzma files"
+The
+.B .lzma
+format allows
+.I lc
+values up to 8, and
+.I lp
+values up to 4.
+LZMA Utils can decompress files with any
+.I lc
+and
+.IR lp ,
+but always creates files with
+.B lc=3
+and
+.BR lp=0 .
+Creating files with other
+.I lc
+and
+.I lp
+is possible with
+.B xz
+and with LZMA SDK.
+.PP
+The implementation of the LZMA1 filter in liblzma
+requires that the sum of
+.I lc
+and
+.I lp
+must not exceed 4.
+Thus,
+.B .lzma
+files, which exceed this limitation, cannot be decompressed with
+.BR xz .
+.PP
+LZMA Utils creates only
+.B .lzma
+files which have a dictionary size of
+.RI "2^" n
+(a power of 2) but accepts files with any dictionary size.
+liblzma accepts only
+.B .lzma
+files which have a dictionary size of
+.RI "2^" n
+or
+.RI "2^" n " + 2^(" n "\-1)."
+This is to decrease false positives when detecting
+.B .lzma
+files.
+.PP
+These limitations shouldn't be a problem in practice,
+since practically all
+.B .lzma
+files have been compressed with settings that liblzma will accept.
+.
+.SS "Trailing garbage"
+When decompressing,
+LZMA Utils silently ignore everything after the first
+.B .lzma
+stream.
+In most situations, this is a bug.
+This also means that LZMA Utils
+don't support decompressing concatenated
+.B .lzma
+files.
+.PP
+If there is data left after the first
+.B .lzma
+stream,
+.B xz
+considers the file to be corrupt unless
+.B \-\-single\-stream
+was used.
+This may break obscure scripts which have
+assumed that trailing garbage is ignored.
+.
+.SH NOTES
+.
+.SS "Compressed output may vary"
+The exact compressed output produced from
+the same uncompressed input file
+may vary between XZ Utils versions even if
+compression options are identical.
+This is because the encoder can be improved
+(faster or better compression)
+without affecting the file format.
+The output can vary even between different
+builds of the same XZ Utils version,
+if different build options are used.
+.PP
+The above means that once
+.B \-\-rsyncable
+has been implemented,
+the resulting files won't necessarily be rsyncable
+unless both old and new files have been compressed
+with the same xz version.
+This problem can be fixed if a part of the encoder
+implementation is frozen to keep rsyncable output
+stable across xz versions.
+.
+.SS "Embedded .xz decompressors"
+Embedded
+.B .xz
+decompressor implementations like XZ Embedded don't necessarily
+support files created with integrity
+.I check
+types other than

+Since the default is

+The

+option to

+sets the number of parallel
+.B xz

+The best value for the
+.B \-n
+option depends on how many files there are to be compressed.
+If there are only a couple of files,
+the value should probably be 1;
+with tens of thousands of files,
+100 or even more may be appropriate to reduce the number of
+.B xz
+processes that
+.BR xargs (1)
+will eventually create.
+.PP
+The option
+.B \-T1
+for
+.B xz
+is there to force it to single-threaded mode, because
+.BR xargs (1)
+is used to control the amount of parallelization.

+.SS "Custom compressor filter chains"
+The simplest use for custom filter chains is
+customizing a LZMA2 preset.
+This can be useful,
+because the presets cover only a subset of the
+potentially useful combinations of compression settings.
+.PP
+The CompCPU columns of the tables
+from the descriptions of the options
+.BR "\-0" " ... " "\-9"
+and

+.TE
+.RE
+.PP
+If you know that a file requires
+somewhat big dictionary (e.g. 32 MiB) to compress well,
+but you want to compress it quicker than
+.B "xz \-8"
+would do, a preset with a low CompCPU value (e.g. 1)
+can be modified to use a bigger dictionary:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-lzma2=preset=1,dict=32MiB foo.tar
+.ft R
+.fi
+.RE
+.PP
+With certain files, the above command may be faster than
+.B "xz \-6"
+while compressing significantly better.
+However, it must be emphasized that only some files benefit from
+a big dictionary while keeping the CompCPU value low.
+The most obvious situation,
+where a big dictionary can help a lot,
+is an archive containing very similar files
+of at least a few megabytes each.
+The dictionary size has to be significantly bigger
+than any individual file to allow LZMA2 to take
+full advantage of the similarities between consecutive files.
+.PP
+If very high compressor and decompressor memory usage is fine,
+and the file being compressed is
+at least several hundred megabytes, it may be useful
+to use an even bigger dictionary than the 64 MiB that
+.B "xz \-9"
+would use:
+.RS
+.PP
+.nf
+.ft CW
+xz \-vv \-\-lzma2=dict=192MiB big_foo.tar
+.ft R
+.fi
+.RE
+.PP
+Using
+.B \-vv
+.RB ( "\-\-verbose \-\-verbose" )
+like in the above example can be useful
+to see the memory requirements
+of the compressor and decompressor.
+Remember that using a dictionary bigger than
+the size of the uncompressed file is waste of memory,
+so the above command isn't useful for small files.
+.PP
+Sometimes the compression time doesn't matter,
+but the decompressor memory usage has to be kept low
+e.g. to make it possible to decompress the file on
+an embedded system.
+The following command uses
+.B \-6e
+.RB ( "\-6 \-\-extreme" )
+as a base and sets the dictionary to only 64\ KiB.
+The resulting file can be decompressed with XZ Embedded
+(that's why there is
+.BR \-\-check=crc32 )
+using about 100\ KiB of memory.
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-check=crc32 \-\-lzma2=preset=6e,dict=64KiB foo
+.ft R
+.fi
+.RE
+.PP
+If you want to squeeze out as many bytes as possible,
+adjusting the number of literal context bits
+.RI ( lc )
+and number of position bits
+.RI ( pb )
+can sometimes help.
+Adjusting the number of literal position bits
+.RI ( lp )
+might help too, but usually
+.I lc
+and
+.I pb
+are more important.
+E.g. a source code archive contains mostly US-ASCII text,
+so something like the following might give
+slightly (like 0.1\ %) smaller file than
+.B "xz \-6e"
+(try also without
+.BR lc=4 ):
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-lzma2=preset=6e,pb=0,lc=4 source_code.tar
+.ft R
+.fi
+.RE
+.PP
+Using another filter together with LZMA2 can improve
+compression with certain file types.
+E.g. to compress a x86-32 or x86-64 shared library
+using the x86 BCJ filter:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-x86 \-\-lzma2 libfoo.so
+.ft R
+.fi
+.RE
+.PP
+Note that the order of the filter options is significant.
+If
+.B \-\-x86
+is specified after
+.BR \-\-lzma2 ,
+.B xz
+will give an error,
+because there cannot be any filter after LZMA2,
+and also because the x86 BCJ filter cannot be used
+as the last filter in the chain.
+.PP
+The Delta filter together with LZMA2
+can give good results with bitmap images.
+It should usually beat PNG,
+which has a few more advanced filters than simple
+delta but uses Deflate for the actual compression.
+.PP
+The image has to be saved in uncompressed format,
+e.g. as uncompressed TIFF.
+The distance parameter of the Delta filter is set
+to match the number of bytes per pixel in the image.
+E.g. 24-bit RGB bitmap needs
+.BR dist=3 ,
+and it is also good to pass
+.B pb=0
+to LZMA2 to accommodate the three-byte alignment:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-delta=dist=3 \-\-lzma2=pb=0 foo.tiff
+.ft R
+.fi
+.RE
+.PP
+If multiple images have been put into a single archive (e.g.\&
+.BR .tar ),
+the Delta filter will work on that too as long as all images
+have the same number of bytes per pixel.

+.SH SYNOPSIS
+.B xzdec
+.RI [ option... ]
+.RI [ file... ]
+.br
+.B lzmadec
+.RI [ option... ]
+.RI [ file... ]
+.SH DESCRIPTION
+.B xzdec
+is a liblzma-based decompression-only tool for
+.B .xz
+(and only
+.BR .xz )
+files.
+.B xzdec
+is intended to work as a drop-in replacement for
+.BR xz (1)
+in the most common situations where a script
+has been written to use
+.B "xz \-\-decompress \-\-stdout"
+(and possibly a few other commonly used options) to decompress
+.B .xz
+files.
+.B lzmadec
+is identical to
+.B xzdec
+except that
+.B lzmadec
+supports
+.B .lzma
+files instead of
+.B .xz
+files.
+.PP
+To reduce the size of the executable,
+.B xzdec
+doesn't support multithreading or localization,
+and doesn't read options from
+.B XZ_DEFAULTS
+and
+.B XZ_OPT
+environment variables.
+.B xzdec
+doesn't support displaying intermediate progress information: sending
+.B SIGINFO
+to
+.B xzdec
+does nothing, but sending
+.B SIGUSR1
+terminates the process instead of displaying progress information.
+.SH OPTIONS

+.SH "EXIT STATUS"

+.B 0
+All was good.
+.TP
+.B 1
+An error occurred.
+.PP
+.B xzdec
+doesn't have any warning messages like
+.BR xz (1)
+has, thus the exit status 2 is not used by
+.BR xzdec .
+.SH NOTES
+Use
+.BR xz (1)
+instead of
+.B xzdec
+or
+.B lzmadec
+for normal everyday use.
+.B xzdec
+or
+.B lzmadec
+are meant only for situations where it is important to have
+a smaller decompressor than the full-featured
+.BR xz (1).
+.PP
+.B xzdec
+and
+.B lzmadec
+are not really that small.
+The size can be reduced further by dropping
+features from liblzma at compile time,
+but that shouldn't usually be done for executables distributed
+in typical non-embedded operating system distributions.
+If you need a truly small
+.B .xz
+decompressor, consider using XZ Embedded.
