makewhatis(8) -- Linux man page



makewhatis - Create the whatis database  


makewhatis [-u] [-v] [-w] [-s sections ] [-c [catpath]] [manpath]  


makewhatis reads all the manual pages contained in the given sections of manpath or the preformatted pages contained in the given sections of catpath. For each page, it writes a line in the whatis database; each line consists of the name of the page and a short description, separated by a dash. The description is extracted using the content of the NAME section of the manual page.

Since other languages use a different term for the NAME section, makewhatis recognizes the equivalent terms in Czech, Italian, Finnish, French, German and Spanish.

If no manpath argument is given, /usr/man is assumed by default.  


Update database with new pages.
Verbose output
Use manpath obtained from `man --path`
-s sections
Looks in the sections of manpath or catpath. If the option is absent, its value is assumed to be '1 2 3 4 5 6 7 8 9 n l'
-c catpath
The preformatted manual pages located in catpath are scanned. If the argument is not provided, it is assumed to be the first existing directory between /usr/man/preformat and /usr/man.

makewhatis may not handle too well manual pages written with non-standard troff macros, such as the Tcl/Tk pages.

makewhatis does not work on preformatted translations.
