NAME
       env - set environment for command invocation

SYNOPSIS
       /usr/bin/env [-i	| -]  [name=value...] [	utility	[ arg... ]]

       /usr/xpg4/bin/env [-i | -]  [name=value...] [ utility [ arg... ]]

DESCRIPTION
       The  env	utility	obtains	the current environment, modifies it according
       to its arguments, then invokes the utility named	by the utility operand
       with the	modified environment.

       Optional	 arguments  are	 passed	 to  utility. If no utility operand is
       specified, the resulting	environment is written to the standard output,
       with one	name=value pair	per line.

   /usr/bin
       If  env	executes  commands  with  arguments, it	uses the default shell
       /usr/bin/sh (see	sh(1)).

   /usr/xpg4/bin
       If env executes commands	with arguments,	it uses	/usr/xpg4/bin/sh  (see
       ksh(1)).

OPTIONS
       The following options are supported:

       -i | -	       Ignores	the environment	that would otherwise be	inher-
		       ited from the current shell.  Restricts the environment
		       for utility to that specified by	the arguments.

OPERANDS
       The following operands are supported:

       name=value      Arguments  of  the form name=value modify the execution
		       environment, and	are placed into	the inherited environ-
		       ment before utility is invoked.

       utility	       The  name  of  the  utility  to be invoked.  If utility
		       names any of the	special	shell built-in utilities,  the
		       results are undefined.

       arg	       A  string  to pass as an	argument for the invoked util-
		       ity.

EXAMPLES
       Example 1: Invoking utilities with new PATH values

       The following utility:

       example%	env -i PATH=/mybin mygrep xyz myfile

       invokes the utility mygrep with a new PATH value	as the only  entry  in
       its  environment.  In  this  case, PATH is used to locate mygrep, which
       then must reside	in /mybin.

ENVIRONMENT VARIABLES
       See environ(5) for descriptions of the following	environment  variables
       that  affect the	execution of env: LANG,	LC_ALL,	LC_CTYPE, LC_MESSAGES,
       and NLSPATH.

       PATH	Determine the location of the utility. If PATH is specified as
		a  name=value operand to env, the value	given shall be used in
		the search for utility.

EXIT STATUS
       If utility is invoked, the exit status of env is	 the  exit  status  of
       utility.	 Otherwise,  the env utility returns one of the	following exit
       values:

       0	Successful completion.

       1-125	An error occurred.

       126	utility	was found but could not	be invoked.

       127	utility	could not be found.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:
