PG(1) User Commands PG(1)
pg - browse pagewise through text files
pg [-amount] [-p prompt] [-cefnrs] [+line] [+/pattern/] [file...]
pg displays a text file on a CRT one screenful at once. After each
page, a prompt is displayed. 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 standard 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 navigation possible.
pg accepts the following options:
+number
Start at the given line number.
+/pattern/
Start at the line containing the Basic Regular Expression
pattern given.
-number
The number of lines per page. By default, 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 Do not pause and display (EOF) at the end of a file.
-f Do 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 normal 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.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
The following commands may be entered at the prompt. Commands
preceded by i in this document 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
relative to the beginning.
i<Enter>
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 relative to the current position.
iw or iz
As <Enter> 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 Expression 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 Expression 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.
The following environment variables affect the behavior of pg:
COLUMNS
Overrides the system-supplied number of columns if set.
LANG, LC_ALL, LC_COLLATE, LC_CTYPE, LC_MESSAGES
See locale(7).
LINES Overrides the system-supplied number of lines if set.
SHELL Used by the ! command.
TERM Determines the terminal type.
cat(1), more(1), sh(1), terminfo(5), locale(7), regex(7), term(7)
pg expects the terminal tabulators to be set every eight positions.
Files that include NUL characters cannot be displayed by pg.
