Other possibilities are enumerated later. +.PP +.I Zmore +looks in the file +.I /etc/termcap +to determine terminal characteristics, +and to determine the default window size. +On a terminal capable of displaying 24 lines, +the default window size is 22 lines. +To use a pager other than the default +.IR more , +set environment variable PAGER to the name of the desired program, such as +.IR less . +.PP +Other sequences which may be typed when +.I zmore +pauses, and their effects, are as follows (\fIi\fP is an optional integer +argument, defaulting to 1) : +.PP +.IP \fIi\^\fP<space> +display +.I i +more lines, (or another screenful if no argument is given) +.PP +.IP ^D +display 11 more lines (a ``scroll''). +If +.I i +is given, then the scroll size is set to \fIi\fP. +.PP +.IP d +same as ^D (control-D) +.PP +.IP \fIi\^\fPz +same as typing a space except that \fIi\fP, if present, becomes the new +window size. +.PP +.IP \fIi\^\fPs +skip \fIi\fP lines and print a screenful of lines +.PP +.IP \fIi\^\fPf +skip \fIi\fP screenfuls and print a screenful of lines +.PP +.IP "q or Q" +Quit. +.PP +.IP = +Display the current line number. +.PP +.IP \fIi\fP/expr +search for the \fIi\^\fP-th occurrence of the regular expression \fIexpr.\fP +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. +.PP +.IP \fIi\^\fPn +search for the \fIi\^\fP-th occurrence of the last regular expression entered. +.PP +.IP !command +invoke a shell with \fIcommand\fP. +The character `!' in "command" is replaced with the +previous shell command. The sequence "\\!" is replaced by "!". +.PP +.IP ":q or :Q" +Quit +(same as q or Q). +.PP +.IP . +(dot) repeat the previous command. +.PP +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 +argument being formed. +In addition, the user may hit the erase character to redisplay the +--More-- message. +.PP +At any time when output is being sent to the terminal, the user can +hit the quit key (normally control\-\\). +.I Zmore +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 terminal's output queue +are flushed when the quit signal occurs. +.PP +The terminal is set to +.I 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. +.PP +If the standard output is not a teletype, then +.I zmore +acts just like +.IR zcat , +except that a header is printed before each file +if there is more than one file. +.SH FILES +.TP +/etc/termcap +Terminal data base +.SH "SEE ALSO" +more(1), gzip(1), zdiff(1), zgrep(1), znew(1), zforce(1), gzexe(1) |
