or reference page).
DESCRIPTION

app13 in the directory /usr/local/man, enter: whereis -M /usr/local/man -f -f appl3 To find the programs in /usr/bin that do not have ref-
erence pages in /usr/share/man/man1 with source files in /usr/src/cmd, enter: whereis -u -M /usr/share/man/man1
-S /usr/src/cmd -f /usr/bin/* To find which files in the current directory either have no reference pages in the default reference
