pg — Display files interactively
Format
Description
Options
pg [–cefnst] [–p prompt] [– screen] [+line] [+/pattern/] [file ...]
Note: The pg utility is fully supported for compatibility with older UNIX systems.
However, it is recommended that the more utility be used instead because it
may provide greater functionality and is considered the standard for portable
UNIX applications as defined by POSIX.2 IEEE standard 1003.2-1992.
pg displays input files or piped output from another command, a screenful at a time.
If you do not specify any files, the standard input (stdin) is read. Any file named –
specifies the stdin.
“Commands” on page 506 lists commands that can be entered at page and file
breaks.
–c Clears the screen before displaying each new window.
–e Eliminates the (EOF): prompt at the end of each file.
–f Does not fold lines. Usually, lines longer than the screen width, as given by
the environment variable COLUMNS are folded into multiple lines. This
option may be useful for files containing device-specific escape sequences.
–n Executes interactive commands immediately after receiving the command
character. This works for most commands. Usually, you must press
for interactive commands.
–p string
Sets the prompt string that appears at the end of each screen of text to
string. The default prompt is a colon (:). If string contains the characters %d,
pg replaces those characters with the current page number as in [Page
%d].
–s Displays all interactive command prompts in standout mode (most often
reverse video) on the screen.
–t Does not save input in a temporary file. Usually, if any of the inputs is not
directly seekable (as is the case for a serial device or pipe), pg reads input
and saves it in a temporary file so that it can be reviewed. Because of this,
you cannot scan backwards when viewing such input. This option is also
recommended when reading a larger amount of data from a stream that
cannot be accommodated on disk.
–screen
Sets the number of lines displayed in each screen to n lines. If you do not
select this option, the number of lines displayed is one less than the
number of lines on the screen as given by the environment variable LINES.
“Commands” on page 506 discusses the w command.
+line Starts printing at line n of the first file. The default is to start printing at line
1.
+/pattern/
Starts printing at the line containing the first occurrence of the extended
regular expression pattern.
