FYI: the -W just limits the command to writable cases.
If the text is not a writable, it will not get a line of output.

FYI: the -T just limits the command to loader tunable cases.
If the text is not loader tunable, it will not get a line of output.

If both -T and -W list the output line, then it is both
loader-tunable and writable. The values will be the same.

I use the -T and -W to discover/report the loader-tunable vs.
writable vs. both status (2 commands). Otherwise the -T and
-W are not necessary on the command lines.
