NAME
       bzmore, bzless - file perusal filter for crt viewing of bzip2 compressed text

SYNOPSIS
       bzmore [ name ...  ]
       bzless [ name ...  ]

NOTE
       In the following description, bzless and less can be used interchangeably with bzmore and more.

DESCRIPTION
       Bzmore  is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy termi‐
       nal.  bzmore works on files compressed with bzip2 and also on uncompressed files.  If a file does not  exist,  bzmore  looks
       for a file of the same name with the addition of a .bz2 suffix.

       Bzmore  normally  pauses after each screenful, printing --More-- at the bottom of the screen.  If the user then types a car‐
       riage return, one more line is displayed.  If the user hits a space, another screenful is  displayed.   Other  possibilities
       are enumerated later.

       Bzmore looks in the file /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  bz‐
       more pauses, and their effects, are as follows (i is an optional integer argument, defaulting to 1) :

       i<space>
              display i more lines, (or another screenful if no argument is given)

       ^D     display 11 more lines (a ``scroll'').  If i is given, then the scroll size is set to i.

       d      same as ^D (control-D)

       iz     same  as  typing  a  space except that i, if present, becomes the new window size.  Note that the window size reverts
              back to the default at the end of the current file.

       is     skip i lines and print a screenful of lines

       if     skip i screenfuls and print a screenful of lines

       q or Q quit reading the current file; go on to the next (if any)

       e or q When the prompt --More--(Next file: file) is printed, this command causes bzmore to exit.

       s      When the prompt --More--(Next file: file) is printed, this command causes bzmore to skip the next file and continue.

       =      Display the current line number.

       i/expr search for the i-th occurrence of the regular expression expr.  If the pattern is not found, 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.

       in     search for the i-th occurrence of the last regular expression entered.

       !command
              invoke  a  shell with command.  The character `!' in "command" are replaced with the previous shell command.  The se‐
              quence "\!" is replaced by "!".

       :q or :Q
              quit reading the current file; go on to the next (if any) (same as q or Q).

       .      (dot) repeat the previous command.

       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 addi‐
       tion, the user may hit the erase character to redisplay the --More-- message.

       At any time when output is being sent to the terminal, the user can hit the quit key (normally control-\).  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.

       The  terminal  is set to 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.

       If the standard output is not a teletype, then bzmore acts just like bzcat, except that a  header  is  printed  before  each
       file.

bzless --help | cat
------> --help <------
bzip2, a block-sorting file compressor.  Version 1.0.6, 6-Sept-2010.

   usage: bzip2 [flags and input files in any order]

   -h --help           print this message
   -d --decompress     force decompression
   -z --compress       force compression
   -k --keep           keep (don't delete) input files
   -f --force          overwrite existing output files
   -t --test           test compressed file integrity
   -c --stdout         output to standard out
   -q --quiet          suppress noncritical error messages
   -v --verbose        be verbose (a 2nd -v gives more)
   -L --license        display software version & license
   -V --version        display software version & license
   -s --small          use less memory (at most 2500k)
   -1 .. -9            set block size to 100k .. 900k
   --fast              alias for -1
   --best              alias for -9

   If invoked as `bzip2', default action is to compress.
              as `bunzip2',  default action is to decompress.
              as `bzcat', default action is to decompress to stdout.

   If no file names are given, bzip2 compresses or decompresses
   from standard input to standard output.  You can combine
   short flags, so `-v -4' means the same as -v4 or -4v, &c.
