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.

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

OPTIONS
       The following options are supported:

       -i | −
		     Ignores the environment that would otherwise be inherited
		     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 utility.

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.
