NAME
pg - browse pagewise through text files
SYNOPSIS
pg [ -number ] [ -p string ] [ -cefnrs ] [ +line ] [ +/pattern/ ] [ file . . . ]
DESCRIPTION
Pg displays a text file on a CRT one screenful at once. After each page, a prompt is dis-
played. The user may then either press the newline key to view the next page or one of the
keys described below.
If no filename is given on the command line, pg reads from standard input. If the stan-
dard output is not a terminal, pg acts like cat(1) but precedes each file with its name if
there is more than one.
If input comes from a pipe, pg stores the data in a buffer file while reading to make nav-
igation possible.
OPTIONS
Pg accepts the following options:
-number
The number of lines per page. Usually, this is the number of CRT lines minus one.
-c Clear the screen before a page is displayed if the terminfo entry for the terminal
provides this capability.
-e pg will not pause and display (EOF) at the end of a file.
-f pg does not split long lines.
-n Without this option, commands must be terminated by a newline character. With this
option, pg advances once a command letter is entered.
-p string
Instead of the prompt : , string is displayed. If string contains %d , its first
occurrence is replaced by the number of the current page.
-r Disallow the shell escape.
-s Print messages in standout mode if the terminfo entry for the terminal provides
this capability.
+number
Start at the given line.
+/pattern/
Start at the line containing the Basic Regular Expression pattern given.
USAGE
The following commands may be entered at the prompt. Commands preceded by i in this docu-
ment accept a number as argument, positive or negative. If this argument starts with + or
-, it is interpreted relative to the current position in the input file, otherwise rela-
tive to the beginning.
i<newline>
Display the next or the indicated page.
id or ^D
Display the next halfpage. If i is given, it is always interpreted relative to the
current position.
il Display the next or the indicated line.
if Skip a page forward. i must be a positive number and is always interpreted rela-
tive to the current position.
iw or iz
Behave as <newline> except that i becomes the new page size.
. or ^L
Redraw the screen.
$ Advance to the last line of the input file.
i/pattern/
Search forward until the first or the i-th occurrence of the Basic Regular Expres-
sion pattern is found. The search starts after the current page and stops at the
end of the file. No wrap-around is performed. i must be a positive number.
i?pattern? or i^pattern^
Search backward until the first or the i-th occurrence of the Basic Regular Expres-
sion pattern is found. The search starts before the current page and stops at the
beginning of the file. No wrap-around is performed. i must be a positive number.
The search commands accept an added letter. If t is given, the line containing the pattern
is displayed at the top of the screen, which is the default. m selects the middle and b
the bottom of the screen. The selected position is used in following searches, too.
in Advance to the next file or i files forward.
ip Reread the previous file or i files backward.
s filename
Save the current file to the given filename.
h Display a command summary.
!command
Execute command using the shell.
q or Q Quit.
If the user presses the interrupt or quit key while pg reads from the input file or writes
on the terminal, pg will immediately display the prompt. In all other situations these
keys will terminate pg.
