sorry i dont want loops ( cause slow and more code )
i did .. [[ ${arr[$1]} ]] check
the other possibility is to use
match='@(a|b|..)' instead of just match='a|b|

If the case construct didn't require a | between different patterns in

i dont get what ur trying there ..
i do IFS=sep and arr[*] to fastly ( i suppose join the elements for further
use )

ah okk u did try in one
i didnt cause i use new ifs and also reset it afterwards

u can try

shopt -s extglob
m=a\|b s=b
 case $s in @($m)) echo ye .. ;;
