DESCRIPTION
The type utility indicates how each argument would be interpreted if used as a command name.
The standard output of type contains information about each parameter. The information provided identifies the operand as a shell built-in, a function, an alias or keyword, and where applicable, displays the command’s pathname.
RESTRICTIONS
For proper execution, 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). If type is called in a separate utility execution environment, such as one of the following it might not produce accurate results.
nohup type writer
find . -type f | xargs type
EXIT STATUS
The following exit values are returned:
0Successful completion.
>0An error occurred.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of type:
LANG
Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization variables contains an invalid setting, the utility behaves as if none of the variables had been defined.
LC_ALL
If set to a non-empty string value, overrides the values of all the other internationalization variables.
LC_CTYPE
Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments).
LC_MESSAGES
Determines the locale that should be used to affect the format and contents of diagnostic messages written to standard error.
NLSPATH
Determines the location of message catalogues for the processing of LC_MESSAGES.
PATH
Determines the location of name.
