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.
