## 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 POSIX.1‐2017, _Section 8.2_ ,
                     _Internationalization Variables_ 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
                     Definitions volume of POSIX.1‐2017, _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.
