       apropos [-dhV] [-e|-w|-r] [-m system[,...]] [-M path] key­
       word ...


       Each manual page has a short description available  within
       it.   apropos  searches  the descriptions for instances of

       keyword is usually a regular expression, as  if  (-r)  was
       used,  or  may  contain wildcards (-w), or match the exact
       keyword (-e).  Using these options, it may be necessary to
       quote  the keyword or escape (\) the special characters to
       stop the shell from interpreting them.

       The standard matching  rules  allow  matches  to  be  made
       against  the page name and word boundaries in the descrip­


       -d, --debug
              Print debugging information.

       -r, --regex
              Interpret each keyword  as  a  regular  expression.
              This  is  the default behaviour.  Each keyword will
              be matched against the page names and the  descrip­
              tions  independently.   It  can  match  any part of
              either.  The match is not limited  to  word  bound­

       -w, --wildcard
              Interpret  each  keyword  as  a  pattern containing
              shell  style  wildcards.   Each  keyword  will   be
              matched against the page names and the descriptions
              independently.  If --exact is also  used,  a  match
              will  only  be found if an expanded keyword matches
              an entire description or page name.  Otherwise  the
              keyword is also allowed to match on word boundaries
              in the description.

       -e, --exact
              Each keyword will be exactly  matched  against  the
              page names and the descriptions.

       -m system[,...], --systems=system[,...]
              If  this  system has access to other operating sys­
              tem's  manual  page  descriptions,  they   can   be
              searched using this option.  To search NewOS's man­
              ual page descriptions, use the option -m NewOS.

              The system specified can be a combination of comma-

       -h, --help
              Print a help message and exit.

       -V, --version
              Display version and author information.


       0      Successful program execution.

       1      Usage, syntax or configuration file error.

       2      Operational error.

       16     Nothing  was found that matched the criteria speci­


       SYSTEM If $SYSTEM is set, it will have the same effect  as
              if  it had been specified as the argument to the -m

              If $MANPATH is set, its value is interpreted as the
              colon-delimited  manual  page hierarchy search path
              to use.

              If $POSIXLY_CORRECT is set, even to a  null  value,
              the  default  apropos search will be as an extended
              regex  (-r) .   Nowadays,  this  is   the   default
              behaviour anyway.


              A traditional global index database cache.

              An alternate or FHS compliant global index database

              A traditional whatis text database.


       whatis(1), man(1).
