Hi,
I don't quite understand this special parameters.
`$-`
: Expands to the current option flags as specified upon invocation,
by the set builtin command, or those set by the shell itself (such as
the -i option).
On my system, I see something like the following. Could anybody
explain what it is? Thanks.
~$ echo $-
himBH
--
Regards,
Peng
