514 Part IV . Running Applications Most man pages are stored in subdirectories of /usr/share/man. Before you create a man page, refer to similar man pages to see the markup and the headings they include. Man1 has commands; man2 has system calls; man3 has library functions; man4 has special device files (/dev/*); man5 has file formats; man6 has games; man7 has miscellaneous components; and man8 has administrative commands. A few other kinds of macros are used in the man page. The .IP macros format indented paragraphs for things such as options. The man page also contains some lower-level font requests; for example, fB says to change the current font to bold, fI changes the font to italic, and fR changes it back to regular font. (This markup is better than asking for a particular font type because it just changes to bold, italic, or regular for the current font.) Figure 20-4 shows what the waycool man page looks like after it is formatted with groff: $ groff -man -Tps -l waycool.1 Figure 20-4: Man page formatting adds headers and lays out the page of text. Table 20-1 lists the macros that you can use on your man pages. These macros are described on the man(7) manual page (type man 7 man to view that page). Tip
