NAME
       command - Treats command arguments as simple commands

SYNOPSIS
       command [-p] command_name [argument...]

       command [-v  | -V] command_name

       The  command  command  causes  the  shell  to  treat the arguments to command as simple commands, and suppresses the default shell function
       lookup.

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       command:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS
       Performs the command search using a default value for PATH that is guaranteed to find all of the standard utilities.  Writes  a	string	to
       standard  output  that indicates the path name or command to be used by the shell in the current shell execution environment to invoke com-
       mand_name.  Writes a string to standard output that indicates how the name given in the command_name operand will  be  interpreted  by  the
       shell in the current shell execution environment.

DESCRIPTION
       The  command  command  allows  you  to run the following commands: User-defined commands whose names correspond to shell built-in commands.
       System commands whose names correspond to shell built-in commands.

       The command_name argument specifies the name of a utility.  The one or more optional arguments to command_name specify strings  treated	as
       arguments to the specified utility.  It also provides information concerning how a command name will be interpreted by the shell.

NOTES
       [Tru64  UNIX]  If  command_name	is  not  the name of a function, the effect of command is the same as would be obtained by specifying com-
       mand_name without command.

RESTRICTIONS
       Since the -v and -V options to command produce output in relation to the current shell execution environment, if command  is  called  in  a
       subshell  or separate utility execution environment, it may not produce correct results.  The following are examples of this type of opera-
       tion:

       (PATH=foo command -v) nohup command -v

EXIT STATUS
       When the -v or -V options are specified, command returns one of the following values.  Successful completion.  The command_name	could  not
       be found, or an error occurred.

       If the -v or -V options are not specified, command returns one of the following values on error.  The utility specified by command_name was
       found but could not be invoked.	An error occurred in the command command, or the utility specified by the command_name argument could  not
       be invoked.

       If no error occurs, the exit status of command is that of the command specified by the arguments to command.

EXAMPLES
       To ensure execution of the simple command pwd instead of the pwd shell built-in command, enter the following: command -p pwd

       The  preceding  command displays the full path name of the current directory, and does not perpetuate a view of the current directory loca-
       tion created by links as the shell built-in command might do.

ENVIRONMENT VARIABLES
       The following environment variables affect the execution of command: 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.  If  set  to  a  non-empty  string
       value,  overrides the values of all the other internationalization variables.  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).  Determines  the  locale  that
       should be used to affect the format and contents of diagnostic messages written to standard error.  Determines the location of message cat-
       alogues for the processing of LC_MESSAGES.  Determines the search path used during the command search unless the -p option is specified.
