NAME

6       bmore - browse through a binary file

SYNOPSIS

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

DESCRIPTION

13       more is a filter that displays the contents of a  binary  file  on  the
14       terminal,  one  screenful  at  a  time.   It normally pauses after each
15       screenful, and prints --More-- at the bottom of the screen.  bmore pro‐
16       vides  a  two-line overlap between screens for continuity.  If bmore is
17       reading from a file rather than a pipe, the  percentage  of  characters
18       displayed so far is also shown.
19
20       bmore  scrolls  up to display one more screen line in response to a RE‐
21       TURN character; it displays another screenful in response  to  a  SPACE
22       character.  Other commands are listed below.
23
24       The  screen is divided in three sections or panes: The byte offset (ex‐
25       treme left), the hex pane (middle), and an  ascii  pane  (right)  which
26       shows  as  printable  characters those bytes in the hex pane.  On an 80
27       column terminal there will be sixteen hex values and their ASCII values
28       on  each  screen  line.  Note that (as one would expect) the first byte
29       has the offset 0 (zero).
30
31       bmore sets the terminal to noecho mode, so that the output can be  con‐
32       tinuous.  Commands that you type do not normally show up on your termi‐
33       nal, except for the / , \ and !  commands.
34
35       If the standard output is not a terminal, more acts just like  cat(1V),
36       except that a header is printed before each file in a series.
37

OPTIONS

39       -a     ASCII mode: no hex representation of the contents. Non printable
40              characters are displayed as a dot (.)
41
42       -c     Clear  before  displaying.  Redrawing  the  screen  instead   of
43              scrolling.
44
45       -d     Display  error messages rather than ringing the terminal bell if
46              an unrecognized command is used.  This is helpful for  inexperi‐
47              enced users.
48
49       -i     Ignore case for searching.
50
51       -n lines
52              Displays the indicated number of lines in each screenful, rather
53              than the default (the number of lines  in  the  terminal  screen
54              less two).
55
56       -r     Characters  between  160  -  254 are displayed as "reverse video
57              text" as used in some legacy systems  (Atari,  Commodore,  Apple
58              II, etc).
59
60       -w cols
61              Display number of cols in each line.
62
63       +linenumber
64              Start up at linenumber.
65
66       +/ASCII-pattern
67              Start  up at the line containing the regular expression pattern.
68              Note: unlike editors, this construct should not end with a  `/'.
69              If  it  does, then the trailing slash is taken as a character in
70              the search pattern.
71

USAGE

73   Commands
74       The commands take effect immediately;  it is not necessary  to  type  a
75       carriage  return.   Up to the time when the command character itself is
76       given, the user may type the line kill character to cancel the  numeri‐
77       cal  argument  being  formed.  In addition, the user may type the erase
78       character to redisplay the `--More--(xx%)' message.
79
80       In the following commands, i is a numerical argument (1 by default).
81
82       iSPACE    Display another screenful, or i more lines if i is specified.
83
84       iRETURN   Display another line, or i more lines, if specified.
85
86       i^D       (CTRL-D) Display (scroll down) 11 more lines.   i  is  given,
87                 the scroll size is set to i.
88
89       id        Same as ^D.
90
91       iz        Same as SPACE, except that i, if present, becomes the new de‐
92                 fault number of lines per screenful.
93
94       is        Skip i lines and then print a screenful.
95
96       if        Skip i screenfuls and then print a screenful.
97
98       i^B       (CTRL-B) Skip back i screenfuls and then print a screenful.
99
100       b         Same as ^B (CTRL-D).
101
102       q
103       Q         Exit from more.
104
105       =         Display the current line number.
106
107       v         Drop into the bvi(1) editor at the current offset of the cur‐
108                 rent file.
109
110       w         Drop into the bvi(1) editor at the current offset of the cur‐
111                 rent file. Only the portion of  the  file  displayed  on  the
112                 screen will be loaded.
113
114       h         Help.  Give a description of all the more commands.
115
116       i/pattern Search  for the ith occurrence of the regular expression pat‐
117                 tern.  Display the screenful starting at  the  file  position
118                 that contains the ith match for the regular expression ASCII-
119                 pattern, or the end of a pipe,  whichever  comes  first.   If
120                 bmore  is  displaying  a file and there is no such match, its
121                 position in the file remains unchanged.  Regular  expressions
122                 can  be edited using erase and kill characters.  Erasing back
123                 past the first column cancels the search command.
124
125       ´         Single quote.  Go to the point from  which  the  last  search
126                 started.   If  no  search  has  been performed in the current
127                 file, go to the beginning of the file.
128
129       !command  Invoke a shell to execute command.  The characters %  and  !,
130                 when  used within command are replaced with the current file‐
131                 name and the previous shell command, respectively.  If  there
132                 is  no  current  filename, % is not expanded. Prepend a back‐
133                 slash to these characters to escape expansion.
134
135       i:n       Skip to the ith next filename given in the command  line,  or
136                 to the last filename in the list if i is out of range.
137
138       i:p       Skip  to the ith previous filename given in the command line,
139                 or to the first filename if i is  out  of  range.   If  given
140                 while  more  is positioned within a file, go to the beginning
141                 of the file.  If more is reading from  a  pipe,  more  simply
142                 rings the terminal bell.
143
144       :f        Display the current filename and offset number.
145
146       :q
147       :Q        Exit from bmore (same as q or Q ).
148
149       .         Dot.  Repeat the previous command.
