I pointed out earlier that // means "global". That makes sense because an empty search would not make sense.
Now RudiC opened my eyes for the /# and /% modifiers. Again, makes sense!

OMG bash-4 comes with even more modifiers:
Code:
 array=( john paul george ringo )
 for btl in ${array[@]}; do echo "$btl"; done 
john
paul
george
ringo
 for btl in ${array[@]^}; do echo "$btl"; done
John
Paul
George
Ringo
 for btl in ${array[@]^^}; do echo "$btl"; done
JOHN
PAUL
GEORGE
RINGO
