NAME

       bmore - browse through a binary file

SYNOPSIS

       bmore [ -acdi ] [ -n lines ] [ -w cols ] [ +linenumber ] [ +/ASCII-pattern ] [ +\Hex-pattern ] [ filename
       ... ]

DESCRIPTION

       more is a filter that displays the contents of a binary file on the terminal, one screenful  at  a  time.
       It normally pauses after each screenful, and prints --More-- at the bottom of the screen.  bmore provides
       a two-line overlap between screens for continuity.  If bmore is reading from a file rather than  a  pipe,
       the percentage of characters displayed so far is also shown.

       bmore  scrolls  up to display one more screen line in response to a RETURN character; it displays another
       screenful in response to a SPACE character.  Other commands are listed below.

       The screen is divided in three sections or panes: The byte offset (extreme left), the hex pane  (middle),
       and  an  ascii  pane  (right)  which shows as printable characters those bytes in the hex pane.  On an 80
       column terminal there will be sixteen hex values and their ASCII values on each screen line.   Note  that
       (as one would expect) the first byte has the offset 0 (zero).

       bmore  sets the terminal to noecho mode, so that the output can be continuous.  Commands that you type do
       not normally show up on your terminal, except for the / , \ and !  commands.

       If the standard output is not a terminal, more acts just like cat(1V), except that a  header  is  printed
       before each file in a series.

OPTIONS

       -a     ASCII mode: no hex representation of the contents. Non printable characters are displayed as a dot
              (.)

       -c     Clear before displaying. Redrawing the screen instead of scrolling.

       -d     Display error messages rather than ringing the terminal bell if an unrecognized command  is  used.
              This is helpful for inexperienced users.

       -i     Ignore case for searching.

       -n lines
              Displays  the  indicated number of lines in each screenful, rather than the default (the number of
              lines in the terminal screen less two).

       -w cols
              Display number of cols in each line.

       +linenumber
              Start up at linenumber.

       +/ASCII-pattern
              Start up at the line containing the  regular  expression  pattern.   Note:  unlike  editors,  this
              construct  should not end with a `/'.  If it does, then the trailing slash is taken as a character
              in the search pattern.

       USAGE

   Commands
       The commands take effect immediately;  it is not necessary to type a carriage return.   Up  to  the  time
       when  the  command  character  itself  is  given, the user may type the line kill character to cancel the
       numerical argument being formed.  In addition, the user may type the erase  character  to  redisplay  the
       `--More--(xx%)' message.

       In the following commands, i is a numerical argument (1 by default).

       iSPACE    Display another screenful, or i more lines if i is specified.

       iRETURN   Display another line, or i more lines, if specified.

       i^D       (CTRL-D) Display (scroll down) 11 more lines.  i is given, the scroll size is set to i.

       id        Same as ^D.

       iz        Same  as  SPACE,  except  that  i,  if  present,  becomes  the  new default number of lines per
                 screenful.

       is        Skip i lines and then print a screenful.

       if        Skip i screenfuls and then print a screenful.

       i^B       (CTRL-B) Skip back i screenfuls and then print a screenful.

       b         Same as ^B (CTRL-D).

       q
       Q         Exit from more.

       =         Display the current line number.

       v         Drop into the bvi(1) editor at the current offset of the current file.

       w         Drop into the bvi(1) editor at the current offset of the current file. Only the portion of  the
                 file displayed on the screen will be loaded.

       h         Help.  Give a description of all the more commands.

       i/pattern Search  for  the  ith  occurrence  of  the  regular  expression pattern.  Display the screenful
                 starting at the file position that contains the ith match for  the  regular  expression  ASCII-
                 pattern,  or the end of a pipe, whichever comes first.  If bmore is displaying a file and there
                 is no such match, its position in the file  remains  unchanged.   Regular  expressions  can  be
                 edited  using erase and kill characters.  Erasing back past the first column cancels the search
                 command.

       ´         Single quote.  Go to the point from which the last search  started.   If  no  search  has  been
                 performed in the current file, go to the beginning of the file.

       !command  Invoke  a  shell  to  execute  command.   The  characters % and !, when used within command are
                 replaced with the current filename and the previous shell command, respectively.  If  there  is
                 no  current  filename,  %  is  not  expanded. Prepend a backslash to these characters to escape
                 expansion.

       i:n       Skip to the ith next filename given in the command line, or to the last filename in the list if
                 i is out of range.

       i:p       Skip  to  the ith previous filename given in the command line, or to the first filename if i is
                 out of range.  If given while more is positioned within a file, go  to  the  beginning  of  the
                 file.  If more is reading from a pipe, more simply rings the terminal bell.

       :f        Display the current filename and offset number.

       :q
       :Q        Exit from bmore (same as q or Q ).

       .         Dot.  Repeat the previous command.
