apropos(1)apropos(1)NAMEapropos - locate commands by keyword lookup
SYNOPSISapropos keyword ...
DESCRIPTIONapropos shows which manual sections contain instances of any of the given
keywords in their title. Each word is considered separately, and, case
of letters is ignored. Words that are parts of other words are
considered; thus, when looking for compile, apropos will also find all
instances of compiler. Try
If the line starts `name(section) ...' you can do `man section name' to
get the documentation for it. Try `apropos format' and then `man 3
printf' to get the manual on the subroutine printf.
apropos is actually just the -k option to the man(1) command.
SEE ALSOmakewhatis(1M), man(1), whatis(1).
CAVEATSapropos (man -k) requires that the whatis database be kept up to date by
running makewhatis(1M) after installing or removing software from the
system. If the whatis database is not kept up to date, apropos (man -k)
will not find entries for new manual pages and will erroneously refer to
manual pages that no longer exist on the system.
