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  screen‐
       ful  at  a  time on a soft-copy terminal.  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 carriage 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 deter‐
       mine  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 bzmore 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.  Eras‐
              ing 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 sequence "\!" 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 addition, 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 (nor‐
       mally  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.  Unfortu‐
       nately, 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.
