The following environment variables shall affect the execution of type:
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.)
If set to a non-empty string value, override the values of
all the other internationalization variables.
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).
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to standard error.
Determine the location of message catalogs for the
processing of LC_MESSAGES.
Determine the location of name, as described in the
Base Definitions volume of IEEE Std 1003.1-2001, Chapter 8,
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.
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
