Shell Programming and Scripting

Hi,

I want to check for the permission of a folder.

Code:

$ ls -ltrd /opt/domains/Logs/docs
drwxr-x---   2 user1      admin        96 Jul  9  2013 /opt/domains/Logs/docs

$ find /opt/domains/Logs -name docs -perm -740
/opt/domains/Logs/docs
$ echo $?
0

$ find /opt/domains/Logs -name docs -perm -744
$ echo $?
0

Looks like the directory [docs] has permissions 750

Now, i wish to alert if the user supplied permission 744 is greater than 750 in the sense

7 5 [0]
7 4 [4]

4>0, but as you can see whether i give a stronger permission[744] or weaker[740], the result is always positive i.e. '0'

How can I check in the if condition , whether the find returned an output or not ?

Code:

x=$(find ...... | wc -l)
if [ $x -eq 0 ]
then
    echo "no output"
    # more statements
fi

Code:

if find ......| grep . >/dev/null
then
    echo "output"
fi
