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.
