TYPE(1P)                   POSIX Programmer's Manual                  TYPE(1P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       type - write a description of command type
SYNOPSIS
       type name...
DESCRIPTION
       The type utility shall indicate how each argument would be  interpreted
       if used as a command name.
OPTIONS
       None.
OPERANDS
       The following operand shall be supported:
       name   A name to be interpreted.

STDIN
       Not used.
INPUT FILES
       None.
ENVIRONMENT VARIABLES
       The following environment variables shall affect the execution of type:
       LANG   Provide  a  default value for the internationalization variables
              that are unset or null. (See  the  Base  Definitions  volume  of
              IEEE Std 1003.1-2001,  Section  8.2,  Internationalization Vari-
              ables for the precedence of internationalization variables  used
              to determine the values of locale categories.)
       LC_ALL If  set  to a non-empty string value, override the values of all
              the other internationalization variables.
       LC_CTYPE
              Determine the locale for  the  interpretation  of  sequences  of
              bytes  of  text  data as characters (for example, single-byte as
              opposed to multi-byte characters in arguments).
       LC_MESSAGES
              Determine the locale that should be used to  affect  the  format
              and contents of diagnostic messages written to standard error.
       NLSPATH
              Determine the location of message catalogs for the processing of
              LC_MESSAGES .
       PATH   Determine the location of name, as described in the Base Defini-
              tions  volume  of  IEEE Std 1003.1-2001,  Chapter 8, Environment
              Variables.

ASYNCHRONOUS EVENTS
       Default.
STDOUT
       The standard output of type contains information about each operand  in
       an  unspecified  format.  The information provided typically identifies
       the operand as a shell built-in, function, alias, or keyword, and where
       applicable, may display the operand's pathname.
STDERR
       The standard error shall be used only for diagnostic messages.
OUTPUT FILES
       None.
EXTENDED DESCRIPTION
       None.
EXIT STATUS
       The following exit values shall be returned:
        0     Successful completion.
       >0     An error occurred.

CONSEQUENCES OF ERRORS
       Default.
       The following sections are informative.
APPLICATION USAGE
       Since type must be aware of the contents of the current shell execution
       environment (such as the lists of commands,  functions,  and  built-ins
       processed  by hash), it is always provided as a shell regular built-in.
       If it is called in a separate utility execution  environment,  such  as
       one of the following:

              nohup type writer
              find . -type f | xargs type
       it might not produce accurate results.
EXAMPLES
       None.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
