| - I thought the placeholder variable _
It isn't really a placeholder variable, it is a magic piece of sh*t
invented by ksh (initially) to fill the role that !$ had in csh
(bash has !$ so it isn't needed for that in bash, and $_ is/was a
VERY poor substitute in any case).
Then it was given all kinds of other meanings in other contexts.
The whole thing is a disaster, just do your best to forget it exists,
and *never* use it for anything.
