John,

If you need to delete non-dupe rows (with my solution rather than a macro), simply filter for FALSE,
then select all the FALSES, and use edit / go to.. Special cells Visible cells only, and delete
the rows. Then turn off the filter.

Thanks for your help. I worked with the next answer because it was simpler.
I will keep your script idea though in case I do need to delete non-dupe rows.
Thanks,

My machine names are in the first column in a spreadsheet. I need to find
or
flag in some way, those instances in which a machine name in one row
is followed by the same name appearing again in the next row's first
column.


It would be fine (but not necessary) to reveal this by deleting all other
rows
that do not repeat in this way.

Thanks,
