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. + +== OPTIONS + +*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. + +include::man-common/help-version.adoc[] + +== COMMANDS + +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. + +__i__**d** or *^D*:: +Display the next halfpage. If _i_ is given, it is always interpreted relative to the current position. + +__i__**l**:: +Display the next or the indicated line. + +__i__**f**:: +Skip a page forward. _i_ must be a positive number and is always interpreted relative to the current position. + +__i__**w** or __i__**z**:: +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. + +__i__**n**:: +Advance to the next file or _i_ files forward. + +__i__**p**:: +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*. + +== ENVIRONMENT + +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. + +== NOTES + +*pg* expects the terminal tabulators to be set every eight positions. + +Files that include NUL characters cannot be displayed by *pg*. + +== SEE ALSO + +*cat*(1), +*more*(1), +*sh*(1p), +*terminfo*(5), +*locale*(7), +*regex*(7), +*term*(7) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] |
