+ <b>--uuid=HEX</b>
+ Enforce that the database UUID (a unique identifier which
+ persists until e.g. the database is compacted) is HEX; exit
+ with an error if it is not. This is useful to detect rollover
+ in modification counts on messages. You can find this UUID
+ using e.g. <b>notmuch</b> <b>count</b> <b>--lastmod</b>
+
+ All global options except <b>--config</b> can also be specified after the com‐
+ mand. For example, <b>notmuch</b> <b>subcommand</b> <b>--uuid=HEX</b> is equivalent to <b>not-</b>
+ <b>much</b> <b>--uuid=HEX</b> <b>subcommand</b>.
