+
+.SH DESCRIPTION
+.I bzip2
+compresses files using the Burrows-Wheeler block sorting
+text compression algorithm, and Huffman coding. Compression is
+generally considerably better than that achieved by more conventional
+LZ77/LZ78-based compressors, and approaches the performance of the PPM
+family of statistical compressors.
+
+The command-line options are deliberately very similar to
+those of
+.I GNU gzip,
+but they are not identical.
+
+.I bzip2
+expects a list of file names to accompany the
+command-line flags. Each file is replaced by a compressed version of
+itself, with the name "original_name.bz2".
+Each compressed file
+has the same modification date, permissions, and, when possible,
+ownership as the corresponding original, so that these properties can
+be correctly restored at decompression time. File name handling is
+naive in the sense that there is no mechanism for preserving original
+file names, permissions, ownerships or dates in filesystems which lack
+these concepts, or have serious file name length restrictions, such as
+MS-DOS.
+
+.I bzip2
+and
+.I bunzip2
+will by default not overwrite existing
+files. If you want this to happen, specify the \-f flag.
+
+If no file names are specified,
+.I bzip2
+compresses from standard
+input to standard output. In this case,
+.I bzip2
+will decline to
+write compressed output to a terminal, as this would be entirely
+incomprehensible and therefore pointless.
+
+.I bunzip2
+(or
+.I bzip2 \-d)
+decompresses all
+specified files. Files which were not created by
+.I bzip2
+will be detected and ignored, and a warning issued.
+.I bzip2
+attempts to guess the filename for the decompressed file
+from that of the compressed file as follows:
+
+ filename.bz2 becomes filename
+ filename.bz becomes filename
+ filename.tbz2 becomes filename.tar
+ filename.tbz becomes filename.tar
+ anyothername becomes anyothername.out
+
+If the file does not end in one of the recognised endings,
+.I .bz2,
+.I .bz,
+.I .tbz2
+or
+.I .tbz,
+.I bzip2
+complains that it cannot
+guess the name of the original file, and uses the original name
+with
+.I .out
+appended.
+
+As with compression, supplying no
+filenames causes decompression from
+standard input to standard output.
+
+.I bunzip2
+will correctly decompress a file which is the
+concatenation of two or more compressed files. The result is the
+concatenation of the corresponding uncompressed files. Integrity
+testing (\-t)
+of concatenated
+compressed files is also supported.
+
+You can also compress or decompress files to the standard output by
+giving the \-c flag. Multiple files may be compressed and
+decompressed like this. The resulting outputs are fed sequentially to
+stdout. Compression of multiple files
+in this manner generates a stream
+containing multiple compressed file representations. Such a stream
+can be decompressed correctly only by
+.I bzip2
+version 0.9.0 or
+later. Earlier versions of
+.I bzip2
+will stop after decompressing
+the first file in the stream.
+
+.I bzcat
+(or
+.I bzip2 -dc)
+decompresses all specified files to
+the standard output.
+
+.I bzip2
+will read arguments from the environment variables
+.I BZIP2
+and
+.I BZIP,
+in that order, and will process them
+before any arguments read from the command line. This gives a
+convenient way to supply default arguments.
+
+Compression is always performed, even if the compressed
+file is slightly
+larger than the original. Files of less than about one hundred bytes
+tend to get larger, since the compression mechanism has a constant
+overhead in the region of 50 bytes. Random data (including the output
+of most file compressors) is coded at about 8.05 bits per byte, giving
+an expansion of around 0.5%.
+
+As a self-check for your protection,
+.I bzip2
+uses 32-bit CRCs to
+make sure that the decompressed version of a file is identical to the
+original. This guards against corruption of the compressed data, and
+against undetected bugs in
+.I bzip2
+(hopefully very unlikely). The
+chances of data corruption going undetected is microscopic, about one
+chance in four billion for each file processed. Be aware, though, that
+the check occurs upon decompression, so it can only tell you that
+something is wrong. It can't help you
+recover the original uncompressed
+data. You can use
+.I bzip2recover
+to try to recover data from
+damaged files.
+
+Unlike
+.I GNU gzip,
+.I bzip2
+will not create a series of
+.I .bz2
+suffixes even when using the
+.I --force
+option:
+
+ filename.bz2 does not become filename.bz2.bz2
+
+Return values: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, &c), 2 to indicate a corrupt
+compressed file, 3 for an internal consistency error (eg, bug) which
+caused
+.I bzip2
+to panic.
+
+.SH OPTIONS
+.TP
+.B \-c --stdout
+Compress or decompress to standard output.
+.TP
+.B \-d --decompress
+Force decompression.
+.I bzip2,
+.I bunzip2
+and
+.I bzcat
+are
+really the same program, and the decision about what actions to take is
+done on the basis of which name is used. This flag overrides that
+mechanism, and forces
+.I bzip2
+to decompress.
+.TP
+.B \-z --compress
+The complement to \-d: forces compression, regardless of the
+invocation name.
+.TP
+.B \-t --test
+Check integrity of the specified file(s), but don't decompress them.
+This really performs a trial decompression and throws away the result.
+.TP
+.B \-f --force
+Force overwrite of output files. Normally,
+.I bzip2
+will not overwrite
+existing output files. Also forces
+.I bzip2
+to break hard links
+to files, which it otherwise wouldn't do.
+
+bzip2 normally declines to decompress files which don't have the
+correct magic header bytes. If forced (-f), however, it will pass
+such files through unmodified. This is how GNU gzip behaves.
+.TP
+.B \-k --keep
+Keep (don't delete) input files during compression
+or decompression.
+.TP
+.B \-s --small
+Reduce memory usage, for compression, decompression and testing. Files
+are decompressed and tested using a modified algorithm which only
+requires 2.5 bytes per block byte. This means any file can be
+decompressed in 2300\ k of memory, albeit at about half the normal speed.
+
+During compression, \-s selects a block size of 200\ k, which limits
+memory use to around the same figure, at the expense of your compression
+ratio. In short, if your machine is low on memory (8 megabytes or
+less), use \-s for everything. See MEMORY MANAGEMENT below.
+.TP
+.B \-q --quiet
+Suppress non-essential warning messages. Messages pertaining to
+I/O errors and other critical events will not be suppressed.
+.TP
+.B \-v --verbose
+Verbose mode -- show the compression ratio for each file processed.
+Further \-v's increase the verbosity level, spewing out lots of
+information which is primarily of interest for diagnostic purposes.
+.TP
+.B \-h \-\-help
+Print a help message and exit.
+.TP
+.B \-L --license -V --version
+Display the software version, license terms and conditions.
+.TP
+.B \-1 (or \-\-fast) to \-9 (or \-\-best)
+Set the block size to 100 k, 200 k ... 900 k when compressing. Has no
+effect when decompressing. See MEMORY MANAGEMENT below.
+The \-\-fast and \-\-best aliases are primarily for GNU gzip
+compatibility. In particular, \-\-fast doesn't make things
+significantly faster.
+And \-\-best merely selects the default behaviour.
+.TP
+.B \--
+Treats all subsequent arguments as file names, even if they start
+with a dash. This is so you can handle files with names beginning
+with a dash, for example: bzip2 \-- \-myfilename.
+.TP
+.B \--repetitive-fast --repetitive-best
+These flags are redundant in versions 0.9.5 and above. They provided
+some coarse control over the behaviour of the sorting algorithm in
+earlier versions, which was sometimes useful. 0.9.5 and above have an
+improved algorithm which renders these flags irrelevant.
+
+.SH MEMORY MANAGEMENT
+.I bzip2
+compresses large files in blocks. The block size affects
+both the compression ratio achieved, and the amount of memory needed for
+compression and decompression. The flags \-1 through \-9
+specify the block size to be 100,000 bytes through 900,000 bytes (the
+default) respectively. At decompression time, the block size used for
+compression is read from the header of the compressed file, and
+.I bunzip2
+then allocates itself just enough memory to decompress
+the file. Since block sizes are stored in compressed files, it follows
+that the flags \-1 to \-9 are irrelevant to and so ignored
+during decompression.
+
+Compression and decompression requirements,
+in bytes, can be estimated as:
+
+ Compression: 400\ k + ( 8 x block size )
+
+ Decompression: 100\ k + ( 4 x block size ), or
+ 100\ k + ( 2.5 x block size )
+
+Larger block sizes give rapidly diminishing marginal returns. Most of
+the compression comes from the first two or three hundred k of block
+size, a fact worth bearing in mind when using
+.I bzip2
+on small machines.
+It is also important to appreciate that the decompression memory
+requirement is set at compression time by the choice of block size.
+
+For files compressed with the default 900\ k block size,
+.I bunzip2
+will require about 3700 kbytes to decompress. To support decompression
+of any file on a 4 megabyte machine,
+.I bunzip2
+has an option to
+decompress using approximately half this amount of memory, about 2300
+kbytes. Decompression speed is also halved, so you should use this
+option only where necessary. The relevant flag is -s.
+
+In general, try and use the largest block size memory constraints allow,
+since that maximises the compression achieved. Compression and
+decompression speed are virtually unaffected by block size.
+
+Another significant point applies to files which fit in a single block
+-- that means most files you'd encounter using a large block size. The
+amount of real memory touched is proportional to the size of the file,
+since the file is smaller than a block. For example, compressing a file
+20,000 bytes long with the flag -9 will cause the compressor to
+allocate around 7600\ k of memory, but only touch 400\ k + 20000 * 8 = 560
+kbytes of it. Similarly, the decompressor will allocate 3700\ k but only
+touch 100\ k + 20000 * 4 = 180 kbytes.
+
+Here is a table which summarises the maximum memory usage for different
+block sizes. Also recorded is the total compressed size for 14 files of
+the Calgary Text Compression Corpus totalling 3,141,622 bytes. This
+column gives some feel for how compression varies with block size.
+These figures tend to understate the advantage of larger block sizes for
+larger files, since the Corpus is dominated by smaller files.

+
+.SH RECOVERING DATA FROM DAMAGED FILES
+.I bzip2
+compresses files in blocks, usually 900\ kbytes long. Each
+block is handled independently. If a media or transmission error causes
+a multi-block .bz2
+file to become damaged, it may be possible to
+recover data from the undamaged blocks in the file.
+
+The compressed representation of each block is delimited by a 48-bit
+pattern, which makes it possible to find the block boundaries with
+reasonable certainty. Each block also carries its own 32-bit CRC, so
+damaged blocks can be distinguished from undamaged ones.
+
+.I bzip2recover
+is a simple program whose purpose is to search for
+blocks in .bz2 files, and write each block out into its own .bz2
+file. You can then use
+.I bzip2
+\-t
+to test the
+integrity of the resulting files, and decompress those which are
+undamaged.
+
+.I bzip2recover
+takes a single argument, the name of the damaged file,
+and writes a number of files "rec00001file.bz2",
+"rec00002file.bz2", etc., containing the extracted blocks.
+The output filenames are designed so that the use of
+wildcards in subsequent processing -- for example,
+"bzip2 -dc rec*file.bz2 > recovered_data" -- processes the files in
+the correct order.
+
+.I bzip2recover
+should be of most use dealing with large .bz2
+files, as these will contain many blocks. It is clearly
+futile to use it on damaged single-block files, since a
+damaged block cannot be recovered. If you wish to minimise
+any potential data loss through media or transmission errors,
+you might consider compressing with a smaller
+block size.
+
+.SH PERFORMANCE NOTES
+The sorting phase of compression gathers together similar strings in the
+file. Because of this, files containing very long runs of repeated
+symbols, like "aabaabaabaab ...\&" (repeated several hundred times) may
+compress more slowly than normal. Versions 0.9.5 and above fare much
+better than previous versions in this respect. The ratio between
+worst-case and average-case compression time is in the region of 10:1.
+For previous versions, this figure was more like 100:1. You can use the
+\-vvvv option to monitor progress in great detail, if you want.
+
+Decompression speed is unaffected by these phenomena.
+
+.I bzip2
+usually allocates several megabytes of memory to operate
+in, and then charges all over it in a fairly random fashion. This means
+that performance, both for compressing and decompressing, is largely
+determined by the speed at which your machine can service cache misses.
+Because of this, small changes to the code to reduce the miss rate have
+been observed to give disproportionately large performance improvements.
+I imagine
+.I bzip2
+will perform best on machines with very large caches.
+
+.SH CAVEATS
+I/O error messages are not as helpful as they could be.
+.I bzip2
+tries hard to detect I/O errors and exit cleanly, but the details of
+what the problem is sometimes seem rather misleading.
+
+This manual page pertains to version 1.1.0 of
+.I bzip2.
+Compressed data created by this version is entirely forwards and
+backwards compatible with the previous public releases, versions
+0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1, 1.0.2 and above, but with the following
+exception: 0.9.0 and above can correctly decompress multiple
+concatenated compressed files. 0.1pl2 cannot do this; it will stop
+after decompressing just the first file in the stream.
+
+.I bzip2recover
+versions prior to 1.0.2 used 32-bit integers to represent
+bit positions in compressed files, so they could not handle compressed
+files more than 512 megabytes long. Versions 1.0.2 and above use
+64-bit ints on some platforms which support them (GNU supported
+targets, and Windows). To establish whether or not bzip2recover was
+built with such a limitation, run it without arguments. In any event
+you can build yourself an unlimited version if you can recompile it
+with MaybeUInt64 set to be an unsigned 64-bit integer.

+The ideas embodied in
+.I bzip2
+are due to (at least) the following
+people: Michael Burrows and David Wheeler (for the block sorting
+transformation), David Wheeler (again, for the Huffman coder), Peter
+Fenwick (for the structured coding model in the original
+.I bzip,
+and many refinements), and Alistair Moffat, Radford Neal and Ian Witten
+(for the arithmetic coder in the original
+.I bzip).
+I am much
+indebted for their help, support and advice. See the manual in the
+source distribution for pointers to sources of documentation. Christian
+von Roques encouraged me to look for faster sorting algorithms, so as to
+speed up compression. Bela Lubkin encouraged me to improve the
+worst-case compression performance.
+Donna Robinson XMLised the documentation.
+The bz* scripts are derived from those of GNU gzip.
+Many people sent patches, helped
+with portability problems, lent machines, gave advice and were generally
+helpful.

+.SH NAME
+bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text
+.SH SYNOPSIS
+.B bzmore
+[ name ... ]
+.br
+.B bzless
+[ name ... ]
+.SH NOTE
+In the following description,
+.I bzless
+and
+.I less
+can be used interchangeably with
+.I bzmore
+and
+.I more.
+.SH DESCRIPTION
+.I Bzmore
+is a filter which allows examination of compressed or plain text files
+one screenful at a time on a soft-copy terminal.
+.I bzmore
+works on files compressed with
+.I bzip2
+and also on uncompressed files.
+If a file does not exist,
+.I bzmore
+looks for a file of the same name with the addition of a .bz2 suffix.
+.PP
+.I Bzmore
+normally pauses after each screenful, printing --More--
+at the bottom of the screen.
+If the user then types a carriage return, one more line is displayed.
+If the user hits a space,
+another screenful is displayed. Other possibilities are enumerated later.
+.PP
+.I Bzmore
+looks in the file
+.I /etc/termcap
+to determine terminal characteristics,
+and to determine the default window size.
+On a terminal capable of displaying 24 lines,
+the default window size is 22 lines.
+Other sequences which may be typed when
+.I bzmore
+pauses, and their effects, are as follows (\fIi\fP is an optional integer
+argument, defaulting to 1) :
+.PP
+.IP \fIi\|\fP<space>
+display
+.I i
+more lines, (or another screenful if no argument is given)
+.PP
+.IP ^D
+display 11 more lines (a ``scroll'').
+If
+.I i
+is given, then the scroll size is set to \fIi\|\fP.
+.PP
+.IP d
+same as ^D (control-D)
+.PP
+.IP \fIi\|\fPz
+same as typing a space except that \fIi\|\fP, if present, becomes the new
+window size. Note that the window size reverts back to the default at the
+end of the current file.
+.PP
+.IP \fIi\|\fPs
+skip \fIi\|\fP lines and print a screenful of lines
+.PP
+.IP \fIi\|\fPf
+skip \fIi\fP screenfuls and print a screenful of lines
+.PP
+.IP "q or Q"
+quit reading the current file; go on to the next (if any)
+.PP
+.IP "e or q"
+When the prompt --More--(Next file:
+.IR file )
+is printed, this command causes bzmore to exit.
+.PP
+.IP s
+When the prompt --More--(Next file:
+.IR file )
+is printed, this command causes bzmore to skip the next file and continue.
+.PP
+.IP =
+Display the current line number.
+.PP
+.IP \fIi\|\fP/expr
+search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
+If the pattern is not found,
+.I bzmore
+goes on to the next file (if any).
+Otherwise, a screenful is displayed, starting two lines before the place
+where the expression was found.
+The user's erase and kill characters may be used to edit the regular
+expression.
+Erasing back past the first column cancels the search command.
+.PP
+.IP \fIi\|\fPn
+search for the \fIi\|\fP-th occurrence of the last regular expression entered.
+.PP
+.IP !command
+invoke a shell with \fIcommand\|\fP.
+The character `!' in "command" are replaced with the
+previous shell command. The sequence "\\!" is replaced by "!".
+.PP
+.IP ":q or :Q"
+quit reading the current file; go on to the next (if any)
+(same as q or Q).
+.PP
+.IP .
+(dot) repeat the previous command.
+.PP
+The commands take effect immediately, i.e., it is not necessary to
+type a carriage return.
+Up to the time when the command character itself is given,
+the user may hit the line kill character to cancel the numerical
+argument being formed.
+In addition, the user may hit the erase character to redisplay the
+--More-- message.
+.PP
+At any time when output is being sent to the terminal, the user can
+hit the quit key (normally control\-\\).
+.I Bzmore
+will stop sending output, and will display the usual --More--
+prompt.
+The user may then enter one of the above commands in the normal manner.
+Unfortunately, some output is lost when this is done, due to the
+fact that any characters waiting in the terminal's output queue
+are flushed when the quit signal occurs.
+.PP
+The terminal is set to
+.I noecho
+mode by this program so that the output can be continuous.
+What you type will thus not show on your terminal, except for the / and !
+commands.
+.PP
+If the standard output is not a teletype, then
+.I bzmore
+acts just like
+.I bzcat,
+except that a header is printed before each file.
