| .SH NAME | |
| bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text | |
| .SH SYNOPSIS | |
| .B bzmore | |
| [ name ... ] | |
| .br | |
| .B bzless | |
| [ name ... ] | |
| .SH NOTE | |
| In the following description, | |
| .I bzless | |
| and | |
| .I less | |
| can be used interchangeably with | |
| .I bzmore | |
| and | |
| .I more. | |
| .SH DESCRIPTION | |
| .I Bzmore | |
| is a filter which allows examination of compressed or plain text files | |
| one screenful at a time on a soft-copy terminal. | |
| .I bzmore | |
| works on files compressed with | |
| .I bzip2 | |
| and also on uncompressed files. | |
| If a file does not exist, | |
| .I bzmore | |
| looks for a file of the same name with the addition of a .bz2 suffix. | |
| .PP | |
| .I Bzmore | |
| 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. | |
| .PP | |
| .I Bzmore | |
| 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. | |
| Other sequences which may be typed when | |
| .I bzmore | |
| 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. Note that the window size reverts back to the default at the | |
| end of the current file. | |
| .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 reading the current file; go on to the next (if any) | |
| .PP | |
| .IP "e or q" | |
| When the prompt --More--(Next file: | |
| .IR file ) | |
| is printed, this command causes bzmore to exit. | |
| .PP | |
| .IP s | |
| When the prompt --More--(Next file: | |
| .IR file ) | |
| is printed, this command causes bzmore to skip the next file and continue. | |
| .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 | |
| If the pattern is not found, | |
| .I bzmore | |
| 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 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" are replaced with the | |
| previous shell command. The sequence "\\!" is replaced by "!". | |
| .PP | |
| .IP ":q or :Q" | |
| quit reading the current file; go on to the next (if any) | |
| (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 Bzmore | |
| 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 bzmore | |
| acts just like | |
| .I bzcat, | |
| except that a header is printed before each file. | |
