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 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 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
       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.
