       command - Treats command arguments as simple commands

       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.

       Interfaces documented on this reference page conform to industry	 stan‐
       dards as follows:

       command:	 XCU5.0

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

       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.

       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  con‐
       cerning how a command name will be interpreted by the shell.

       [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  command_name
       without command.

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

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

       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  com‐
       mand,  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.

       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 direc‐
       tory,  and does not perpetuate a view of the current directory location
       created by links as the shell built-in command might do.

       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	multi‐
       byte  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 catalogues for
       the processing of LC_MESSAGES.  Determines the search path used	during
       the command search unless the -p option is specified.

       Commands:  env(1), hash(1), type(1)

       Standards:  standards(5)
