env(1)                           User Commands                          env(1)



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.
