BZMORE(1)                                                                                          BZMORE(1)



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 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 suf-fix. suffix.
       fix.

       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  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 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.  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 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 (normally con-trol-\). control-\).
       trol-\).  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.
