- .TH WHATIS 5
- .SH NAME
- whatis - database of online manual pages
- .SH SYNOPSIS
- .B /usr/man/*/whatis
- .br
- .B /usr/man/whatis
- .SH DESCRIPTION
- The
- .B whatis
- file in each manual page directory is a database of titles for manual pages.
- This database is used by
- .BR man (1)
- to map titles to manual pages names. The database is created by
- .BR makewhatis (1)
- from the NAME sections of the manual pages.
- .PP
- The NAME secions must be simple lines with no troff fluff but one
- backslash like these two:
- .PP
- .RS
- whatis e- database of online manual pages
- .br
- cawf, nroff e- C version of the nroff-like, Amazingly Workable (text)
- Formatter
- .RE
- .PP
- These lines are transformed by
- .B makewhatis
- to these two lines for the database:
- .PP
- .RS
- cawf, nroff (1) - C version of the nroff-like, Amazingly Workable (text)
- Formatter
- .br
- whatis (5) - database of online manual pages
- .RE
- .PP
- As you can see they are in section number order, so that
- .B man
- searches them in section order.
- .PP
- Each entry is just a single line, restricting the NAME section to a single
- line too with just one dash, and commas and spaces before the dash as you
- see above.
- .SH "SEE ALSO"
- .BR man (1),
- .BR whatis (1),
- .BR makewhatis (1),
- .BR man (7).
- .SH BUGS
- It seems to be impossible for many manual page writers to keep the NAME
- section simple. They also like to use every font available in their
- documents. My simple scripts can't read their NAME sections, my simple
- me can't read their texts.
