This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface

       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.

       Default.

       Default.

IEEE/The Open Group                                   2017                                          TYPE(1POSIX)

       The type utility shall indicate how each argument would be interpreted if used as a command name.

       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, Section8.2, InternationalizationVariables 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,
                 Chapter8, EnvironmentVariables.

       None.

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

       None.

       None.

       None.

       type — write a description of command type

       The following operand shall be supported:

       name      A name to be interpreted.

       None.

       None.

       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.

       The standard error shall be used only for diagnostic messages.

       Not used.

       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.
