The option .Ar name=value specifies an environmental variable, .Ar name , with a value of .Ar value . The option .Sq Fl i causes .Nm env to completely ignore the environment it inherits. .Pp If no .Ar command is specified, .Nm env prints out the names and values of the variables in the environment, with one name/value pair per line. .Sh DIAGNOSTICS If the .Ar command is invoked, the exit status of .Nm env shall be the exit status of .Ar command ; otherwise, the .Nm env command exits with one of the following values: .Bl -tag -width Ds .It 0 The .Nm env command completed successfully .It 1-125 An error occured. .It 126 The .Ar command was found, but could not be invoked. .It 127 The .Ar command could not be found. .El .Sh SEE ALSO .Xr execvp 3 , .Xr environ 7 .Sh STANDARDS The .Nm env command is expected to be .St -p1003.2 compliant. .Sh BUGS .Nm env doesn't handle commands with equal (``='') signs in their names, for obvious reasons.
