ZMORE(1)	       DragonFly General Commands Manual	      ZMORE(1)

NAME

zmore, zless -- view compressed files

SYNOPSIS

zmore [flags] [file ...] zless [flags] [file ...]

DESCRIPTION

zmore is a filter that allows the viewing of files compressed with Lem- pel-Ziv encoding. Such files generally have a ``Z'' or ``gz'' extension (both the compress(1) and gzip(1) formats are supported). Any flags that are specified are passed to the user's preferred PAGER (which is /usr/bin/more by default). zless is equivalent to zmore but uses less(1) as a pager instead of more(1). When multiple files are specified, zmore will pause at the end of each file and present the following prompt to the user: prev_file (END) - Next: next_file Where prev_file is the file that was just displayed and next_file is the next file to be displayed. The following keys are recognized at the prompt: e or q quit zmore. s skip the next file (or exit if the next file is the last). If no files are specified, zmore will read from the standard input. In this mode zmore will assume gzip(1) style compression since there is no suffix on which to make a decision.

ENVIRONMENT

PAGER Program used to display files. If unset, /usr/bin/more is used (zmore) or /usr/bin/less (zless).

NAME

zmore - file perusal filter for crt viewing of compressed text

SYNOPSIS

zmore [ name ... ]

DESCRIPTION

Zmore is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal. zmore works on files compressed with compress, pack or gzip, and also on uncompressed files. If a file does not exist, zmore looks for a file of the same name with the addition of a .gz, .z or .Z suffix. Zmore 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 possibilities are enumerated later. Zmore looks in the file /etc/termcap to determine terminal characteris- tics, 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 more, set environment variable PAGER to the name of the desired program, such as less. Other sequences which may be typed when zmore 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 Quit. = Display the current line number. i/expr search for the i-th occurrence of the regular expression expr. 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 entered. !command invoke a shell with command. The character `!' in "command" is replaced with the previous shell command. The sequence "\!" is replaced by "!". :q or :Q Quit (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 argument being formed. In addition, the user may hit the erase charac- ter to redisplay the --More-- message. At any time when output is being sent to the terminal, the user can hit the quit key (normally control-\). 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. 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 zmore acts just like zcat, except that a header is printed before each file if there is more than one file.
