ENV(1)				   BSD General Commands Manual				   ENV(1)

     env -- set and print environment

     env [-i] [name=value ...] [utility [argument ...]]

     env executes utility after modifying the environment as specified on the command line.  The
     option name=value specifies an environmental variable, name, with a value of value.  The
     option '-i' causes env to completely ignore the environment it inherits.

     If no utility is specified, env prints out the names and values of the variables in the
     environment, with one name=value pair per line.

     env exits with one of the following values:

     0	     utility was invoked and completed successfully.  In this case the exit code is
	     returned by the utility itself, not env.  If no utility was specified, then env com-
	     pleted successfully and returned the exit code itself.

     1	     An invalid command line option was passed to env.

     1-125   utility was invoked, but failed in some way; see its manual page for more informa-
	     tion.  In this case the exit code is returned by the utility itself, not env.

     126     utility was found, but could not be invoked.

     127     utility could not be found.

     The historic - option has been deprecated but is still supported in this implementation.

     execvp(3), environ(7)

     The env utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

     env doesn't handle commands with equal (``='') signs in their names, for obvious reasons.
