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  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
              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.
