type name...
The
type utility shall indicate how each argument would be interpreted if
used as a command name.
None.
The following operand shall be supported:
- name
- A name to be interpreted.
Not used.
None.
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.
Default.
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.
The standard error shall be used only for diagnostic messages.
None.
None.
The following exit values shall be returned:
- 0
- Successful completion.
- >0
- An error occurred.
Default.
The following sections are informative.
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.
None.
None.
None.
command ,
hash
