MORE(1) General Commands Manual MORE(1) NAME more, page - file perusal filter for crt viewing SYNOPSIS more [ -d ] [ -f ] [ -l ] [ -n ] [ +linenumber ] [ +/pattern ] [ name ... ] page [ -d ] [ -f ] [ -l ] [ -n ] [ +linenumber ] [ +/pattern ] [ name ... ] DESCRIPTION More is a filter which allows examination of a continuous text one screen- ful at a time on a soft-copy terminal. It 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 possibilites are enumerated later. The command line options are: -n An integer which is the size (in lines) of the window which more will use instead of the default. -d More will prompt the user with the message "Hit space to continue, Rubout to abort" at the end of each screenful. This is useful if more is being used as a filter in some setting, such as a class, where many users may be unsophisticated. -f This causes more to count logical, rather than screen lines. That is, long lines are not folded. This option is recommended if nroff output is being piped through ul, since the latter may generate es- cape sequences. These escape sequences contain characters which would ordinarily occupy screen postions, but which do not print when they are sent to the terminal as part of an escape sequence. Thus more may think that lines are longer than they actually are, and fold lines erroneously. -l Do not treat ^L (form feed) specially. If this option is not given, more will pause after any line that contains a ^L, as if the end of a screenful had been reached. Also, if a file begins with a form feed, the screen will be cleared before the file is printed. +linenumber Start up at linenumber. +/pattern Start up two lines before the line containing the regular expression pattern. If the program is invoked as page, then the screen is cleared before each screenful is printed (but only if a full screenful is being printed), and k - 1 rather than k - 2 lines are printed in each screenful, where k is the number of lines the terminal can display. More looks in the file /etc/termcap to determine terminal characteristics, and to determine the default window size. On a terminal capable of dis- playing 24 lines, the default window size is 22 lines. If more is reading from a file, rather than a pipe, then a percentage is displayed along with the --More-- prompt. This gives the fraction of the file (in characters, not lines) that has been read so far. Other sequences which may be typed when more 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 argument 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. is skip i lines and print a screenful of lines if skip i screenfuls and print a screenful of lines q or Q Exit from more. = Display the current line number. v Start up the editor vi at the current line. h Help command; give a description of all the more commands. i/expr search for the i-th occurrence of the regular expression expr. If there are less than i occurrences of expr, and the input is a file (rather than a pipe), then the position in the file remains un- changed. 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 en- tered. ' (single quote) Go to the point from which the last search started. If no search has been performed in the current file, this command goes back to the beginning of the file. !command invoke a shell with command. The characters `%' and `!' in "com- mand" are replaced with the current file name and the previous shell command respectively. If there is no current file name, `%' is not expanded. The sequences "\%" and "\!" are replaced by "%" and "!" respectively. i:n skip to the i-th next file given in the command line (skips to last file if n doesn't make sense) i:p skip to the i-th previous file given in the command line. If this command is given in the middle of printing out a file, then more goes back to the beginning of the file. If i doesn't make sense, more skips back to the first file. If more is not reading from a file, the bell is rung and nothing else happens. :f display the current file name and line number. :q or :Q exit from more (same as q or Q). . (dot) repeat the previous command. The commands take effect immediately, i.e., it is not necessary to type a carriage return. Up to the time when the command character itself is given, the user may hit the line kill character to cancel the numerical ar- gument being formed. In addition, the user may hit the erase character to redisplay the --More--(xx%) message. At any time when output is being sent to the terminal, the user can hit the quit key (normally control-\). More 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 ter- minal'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 more acts just like cat, ex- cept that a header is printed before each file (if there is more than one). A sample usage of more in previewing nroff output would be nroff -ms +2 doc.n | more AUTHOR Eric Shienbrood FILES /etc/termcap Terminal data base /usr/lib/more.help Help file SEE ALSO script(1) 4th Berkeley Distribution 9/25/80 MORE(1)
