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

       env:  XCU5.0

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

OPTIONS
       Invokes utility with exactly the environment  specified	by  the	 argu‐
       ments; the inherited environment is ignored completely.	Changes are in
       effect only while the specified command is running.  Dash is equivalent
       to -i option.

OPERANDS
       Changes	in  the	 form  name=value are added to the current environment
       before the command is run.  [Tru64 UNIX]	 Name of an environment	 vari‐
       able  to be printed.  Name of a command to be invoked with the modified
       environment.  Arguments to be passed to command when it is executed.

DESCRIPTION
       The env command lets you get and change your current  environment,  and
       then run the specified command with the changed environment.  If the -i
       option is used, the current environment is ignored and the command runs
       with  only  the	changed environment.  Changes are only in effect while
       the specified command is running.

       If command is not specified, env displays your current environment, one
       name=value pair per line.

       [Tru64 UNIX]  The printenv command displays the values of the variables
       in the environment.  If name is specified, only its value  is  printed.
       If name is not the name of a currently set environment variable, only a
       blank line is printed, no error is reported.  If name is not specified,
       printenv displays the current environment, one name=value per line.

EXIT STATUS
       If  command  is	invoked,  the exit status of env is the exit status of
       command; otherwise, the env utility exits with  one  of	the  following
       values:	The  env utility completed successfully.  An error occurred in
       the env utility.	 The command specified by command was found but	 could
       not be invoked.	The command specified by command could not be found.

EXAMPLES
       To add a shell variable to the environment for the duration of one com‐
       mand (sh only), enter: TZ=MST7MDT date env TZ=MST7MDT date

	      Each of these commands displays the current  date	 and  time  in
	      Mountain	Standard Time.	The two commands shown are equivalent.
	      When date is finished, the previous value	 of  TZ	 takes	effect
	      again.   To replace the environment with another one, enter: env
	      -i PATH=$PATH IDIR=/u/jim/include LIBDIR=/u/jim/lib make

	      This runs make in an environment that  consists  only  of	 these
	      definitions  for PATH, IDIR, and LIBDIR.	You must redefine PATH
	      so that the shell can find the make command.

	      When make is finished, the  previous  environment	 takes	effect
	      again.   To  find	 the  current  setting of the TERM environment
	      variable, enter: printenv TERM

	      The command returns the value for the TERM environment variable.

ENVIRONMENT VARIABLES
       The following environment variables affect the execution of  env:  Pro‐
       vides  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 vari‐
       ables contain an invalid setting, the utility behaves as if none of the
       variables  had been defined.  If set to a non-empty string value, over‐
       rides 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 for the format
       and contents of diagnostic messages written to standard error.	Deter‐
       mines  the location of message catalogues for the processing of LC_MES‐
       SAGES.
