simple way..

[superstarjpmc]

Can anyone suggest me to devise a script, which achieves the following functionality.

a) Find all Files which has group+ world..write access

eg.
-rw-rw-rw- 1 swnet swnetg 0 Feb 4 13:45 test.file

b) All files/directories whose 'unix group' is owned by 'nobody'. ( 'nobody' is name of unix grp ).

cheers
david

man find

Second question first:

find / -group nobody

Using find, you have to be very specific about all three groups of permissions. For example, if you use

find . -perm u+r,u+w,u+x

you will get a list of files which have read, write, and execute permissions for only the user/owner and no one else.

Here's a very inefficient way

find /my_path -ls | sed -e 's/^ *//g' | tr -s ' ' ';' > file_list.txt
for LINE in `cat file_list.txt`; do
    PERM=`echo $LINE | cut -d";" -f3`
    NAME=`echo $LINE | cut -d";" -f11`

    USER=`echo "$PERM" | cut -c2-4`
    GROUP=`echo "$PERM" | cut -c5-7`
    WORLD=`echo "$PERM" | cut -c8-10`

    CHECKGW=`echo "$GROUP" | grep "w" | wc -l`
    CHECKWW=`echo "$WORLD" | grep "w" | wc -l`

    if [ $((CHECKGW + $CHECKWW)) -eq 2 ]; then
        echo "$PERM\t$NAME"
    fi
done
