OpenSolaris 2009.06 - man page for env (opensolaris section 1)

env(1)					  User Commands 				   env(1)

       env - set environment for command invocation

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

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

       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  result-
       ing 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

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

       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 argu-

       The following operands are supported:

       name=value     Arguments of the form name=value modify the execution environment, and  are
		      placed into the inherited environment 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.

       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.

       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  oper-
	       and to env, the value given shall be used in the search for utility.

       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.

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

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       |CSI			     |enabled			   |
