gzmore - file perusal filter for crt viewing of compressed text
gzmore [ name ... ]
Gzmore is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal. gzmore works on files compressed with compress, pack or gzip, and also on uncompressed files. If a file does not exist, gzmore looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
Gzmore 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.
Gzmore looks in the file /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 more, set environment variable PAGER to the name of the desired program, such as less.
Other sequences which may be typed when gzmore pauses, and their effects, are as follows (i is an optional integer argument, defaulting to 1) :
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.
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. Note that the window size reverts back to the default at the end of the current file. is skip i lines and print a screenful of lines if skip i screenfuls and print a screenful of lines q or Q quit reading the current file; go on to the next (if any) e or q When the prompt --More--(Next file: file) is printed, this command causes gzmore to exit. s When the prompt --More--(Next file: file) is printed, this command causes gzmore to skip the next file and continue. = Display the current line number. i/expr search for the i-th occurrence of the regular expression expr. If the pattern is not found, gzmore goes on to the next file (if any). Otherwise, a screenful is displayed, starting two lines before the place where the expression was found. The users 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 reading the current file; go on to the next (if any) (same as q or Q). . (dot) repeat the previous command.
At any time when output is being sent to the terminal, the user can hit the quit key (normally control-\). Gzmore 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 terminals 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 gzmore acts just like gzcat, except that a header is printed before each file.
