Files perusal filters for CRTs.
| -number | An integer specifying the size (in lines) of the window that pg is to use instead of the default. (On a terminal containing 24 lines, the default window size is 23). |
| -p string | pg uses string as the prompt. If the prompt string contains a %d, the first occurrence of %d in the prompt will be replaced by the current page number when the prompt is issued. The default prompt string is ``:''. |
| -c | Home the cursor and clear the screen before displaying each page. This option is ignored if clear_screen is not defined for this terminal type in the terminfo(4) data base. |
| -e | pg does not pause at the end of each file. |
| -f | Normally, pg splits lines longer than the screen width, but some sequences of characters in the text being displayed (for instance, escape sequences for underlining) generate undesirable results. The -f option inhibits pg from splitting lines. |
| -n | Normally, commands must be terminated by a <new line> character. This option causes an automatic end of command as soon as a command letter is entered |
| -r | Restricted mode. The shell escape is disallowed. pg prints an error message but does not exit. |
| -s | pg prints all messages and prompts in the standard output mode (usually inverse video). |
| +linenumber | Start up at linenumber. |
| |/pattern/ | Start up at the first line containing the regular expression pattern. |
| filename | A path name of a text file to be displayed. If no filename is given, or if it is -, the standard
input is read. |
pg myfile.txt - Would execute and display the file myfile.txt.
