The option .Ar name=value specifies an environmental variable, .Ar name , with a value of .Ar value . The option .Sq Fl i causes .Nm to completely ignore the environment it inherits. .Pp If no .Ar utility is specified, .Nm prints out the names and values of the variables in the environment, with one .Ar name=value pair per line. .Sh DIAGNOSTICS If the .Ar utility is invoked, the exit status of .Nm shall be the exit status of .Ar utility; otherwise, the .Nm utility exits with one of the following values: .Bl -tag -width Ds .It 0 The .Nm utility completed successfully .It 1-125 An error occurred in the .Nm utility. .It 126 The utility specified by .Ar utility was found, but could not be invoked. .It 127 The utility specified by .Ar utility could not be found. .El .Sh COMPATIBILITY The historic .Fl option has been deprecated but is still supported in this implementation. .Sh SEE ALSO .Xr execvp 3 , .Xr environ 7 .Sh STANDARDS The .Nm utility conforms to .St -p1003.2-92 . .Sh BUGS .Nm doesn't handle commands with equal .Pq Dq = signs in their names, for obvious reasons.
