shell script to print/check directory permissions on Unix

Shell script to print/check directory permissions on Unix
Here is a small shell script which will print a directory permissions and other details...
Basically I want to check whether a directory has the read write permissions for the user?
I am using here a simple commonsense that a read write permissions will make the octal permissions of it more than 600 for sure .. that's it.
d rwx rwx rwx
d rw- --- ---
   420 000 000
   6     0      0
   rwx r-x r-x
   7 5 5
So it should be always greater than 600 for a directory to have read write permissions always.
Basically I'm using stat tool to find the permissions of a dir
Ex : check stat for /opt/a
nc184120:/opt # stat /opt/a
  File: `/opt/a'
  Size: 48              Blocks: 0          IO Block: 4096   directory
Device: 802h/2050d      Inode: 101912      Links: 2
Access: (0155/d--xr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)
Access: 2010-07-01 22:53:59.845347264 -0700
Modify: 2010-07-01 01:45:43.769709152 -0700
Change: 2010-07-01 01:46:14.790993200 -0700

So the above script doesn't have read or write permissions.

Shell script  :
nc184120:/opt # cat per.sh
dir="/opt/a"
echo "Checking the permissions for $dir"
stat $dir
echo "##############################################"
if [ `stat -c "%a" $dir` -ge 600 ] ; then
     echo "$dir has Read Write permissions."
else
     echo "$dir has no read write permissions."
fi

and the output looks like below ...
nc184120:/opt # ./per.sh
Checking the permissions for /opt/a
  File: `/opt/a'
  Size: 48              Blocks: 0          IO Block: 4096   directory
Device: 802h/2050d      Inode: 101912      Links: 2
Access: (0155/d--xr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)
Access: 2010-07-01 22:53:59.845347264 -0700
Modify: 2010-07-01 01:45:43.769709152 -0700
Change: 2010-07-01 01:46:14.790993200 -0700
##############################################
/opt/a has no read write permissions.

Who ever writes Inappropriate/Vulgar comments to context, generally want to be anonymous …So I hope U r not the one like that?
For lazy logs u can at least use Name/URL option which don’t even require any sign-in, good thing is that it can accept your lovely nick name also and URL is not mandatory too.
Thanks for your patience
