the '$' will match 'end-of-string', which means EOF unless you use 
<nomultiline> flag, eg:

$ printf '123\n456\n7890\n' |\
$	crm '-{match (:: :x:) /(...)$/; output /-:*:x:-\n/}'
-90
-

note that '.' matched last \n before EOF.

$ printf '123\n456\n7890\n' |\
$	crm '-{match <nomultiline> (:: :x:) /(...)$/; output /-:*:x:-\n/}'
-123-
