I've tried

ls -l | cut -f1 d" " | grep ".{4}rw.{4}"

for example

drwxrwx--x folder folder 4096 sep 3 19:01 dir2

I cut off first colomn and find match with "rw"

but nothing happens

When searching for files by name, size, or other properties you can't go wrong with find. For your use case try -perm -{mode}, which finds files with all of the {mode} bits set. You can use a numeric mode like 030 or the symbolic version, g=rw:

find * -perm -g=rw                 # search subdirectories
find * -maxdepth 0 -perm -g=rw     # current directory only

Here's the full description of the different -perm options from the find(1) man page:

-perm mode
       File's permission bits are exactly mode (octal or
       symbolic).  Since an exact match is required, if you want
       to use this form for symbolic modes, you may have to
       specify a rather complex mode string.  For example `-perm
       g=w' will only match files which have mode 0020 (that is,
       ones for which group write permission is the only
       permission set).  It is more likely that you will want to
       use the `/' or `-' forms, for example `-perm -g=w', which
       matches any file with group write permission.  See the
       EXAMPLES section for some illustrative examples.

-perm -mode
       All of the permission bits mode are set for the file.
       Symbolic modes are accepted in this form, and this is
       usually the way in which you would want to use them.  You
       must specify `u', `g' or `o' if you use a symbolic mode.
       See the EXAMPLES section for some illustrative examples.

-perm /mode
       Any of the permission bits mode are set for the file.
       Symbolic modes are accepted in this form.  You must
       specify `u', `g' or `o' if you use a symbolic mode.  See
       the EXAMPLES section for some illustrative examples.  If
       no permission bits in mode are set, this test matches any
       file (the idea here is to be consistent with the behaviour
       of -perm -000).
