This makes no sense at all.
The <<< operator is followed by a WORD. Not by a LIST.
"$@" expands to a LIST.
Did you intend for grep to iterate through the positional parameters,
and only print the parameters that match your "ptrn"? If so, this code
does not achieve that.
Also, you failed to quote "$ptrn".
