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 vari-
                 ables that are unset or null. (See the Base Definitions  vol-
                 ume  of POSIX.1-2008, 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 Def-
                 initions volume of POSIX.1-2008, Chapter 8, Environment Vari-
                 ables.
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.
