  53 .Sh DESCRIPTION
  54 .Nm
  55 executes
  56 .Ar utility
  57 after modifying the environment as
  58 specified on the command line.  The option
  59 .Ar name=value
  60 specifies
  61 an environmental variable,
  62 .Ar name  ,
  63 with a value of
  64 .Ar value  .
  65 The option
  66 .Sq Fl i
  67 causes
  68 .Nm
  69 to completely ignore the environment
  70 it inherits.
  71 .Pp
  72 If no
  73 .Ar utility
  74 is specified,
  75 .Nm
  76 prints out the names and values
  77 of the variables in the environment, with one
  78 .Ar name=value
  79 pair per line.
  80 .Sh DIAGNOSTICS
  81 If the
  82 .Ar utility
  83 is invoked, the exit status of
  84 .Nm
  85 shall be the exit status of
  86 .Ar utility;
  87 otherwise, the
  88 .Nm
  89 utility exits with one of the following values:
  90 .Bl -tag -width Ds
  91 .It 0
  92 The
  93 .Nm
  94 utility completed successfully
  95 .It 1-125
  96 An error occurred in the
  97 .Nm
  98 utility.

 102 was found, but could not be invoked.
 103 .It 127
 104 The utility specified by
 105 .Ar utility
 106 could not be found.

 115 .Sh STANDARDS
 116 The
 117 .Nm
 118 utility conforms to

 122 doesn't handle commands with equal
 123 .Pq Dq =
 124 signs in their
 125 names, for obvious reasons.
