BZMORE(1) UNIX Programmer's Manual BZMORE(1)NAME
bzmore, bzless - file perusal filter for crt viewing of
bzip2 compressed text
SYNOPSISbzmore [ 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 ter-
minal. 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 possi-
bilities 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 argu-
ment 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 expres-
sion 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 "com-
mand" 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 neces-
sary to type a carriage return. Up to the time when the com-
mand 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.
