Ya se complica un poco, pero ganamos flexibilidad:

$ shopt -s nocaseglob     ## esta es la magia
$ ls foo*
foo.a  foo.A  foo.b  foo.c  foo.sh
$ cat foo.sh
for I in *; do
  OK=0
  for J in ${EXTENSIONES[*]}; do    ## recorrer array
    [[ $I =~ "\.$J" ]] && OK=1      ## mejorable
  done
  [ z$OK == z1 ] && echo $I
done
$ EXTENSIONES=(a b)       ## array
$ . foo.sh
foo.a
foo.A
foo.b
$ EXTENSIONES=(a c)
$ . foo.sh
foo.a
foo.A
foo.c
$ EXTENSIONES=(c b)
$ . foo.sh
foo.b
foo.c
