/dev/sdb: Unknown USB bridge [0x0781:0x558c (0x1012)]

You can try passing the -d sat parameter like this:

# smartctl -d sat -a /dev/sdb
smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.14.0-1008-oem] (local build)

Don’t forget to check out the manpages for smartctl. It has a comprehensive list of options to pass.

Copy a MySQL table

Not using this all too often, so here it is for me and everyone:

create table my_new_table like my_old_table;
