Find File Permissions

[Unix find permissions]

Hi, I am wanting to find all directories and files within a directory structure that do not have universal write access. I know that { find [filename] -perm -2 -print } will find all with universal write access, but just can't work out how to change it to those without universal access. Any help on this would be greatly appreciated. Thanks

For files
find /dir -type f !\( -perm 0002 -o ! -perm 002 ) -exec ll -d {} \;

For dirs
find /dir -type d \( ! -perm 0002 -o ! -perm 002 \) -exec ll -d {} \;

Hello,

You can ! with find

# find /dir -type f !\( -perm 0002 -o ! -perm 002 ) -exec ls -l {} \;

Hi,
the "!" is the logical not.
So reversing your find condition should get you the data.

find . ! -perm -2

Simply as,

# find . \( -type d -o -type f \) ! -perm -002

Maybe that is not exactly what I am wanting to find out. I think what I really want to know is which files are unable to be writen to by the user I am logged in as. So if I am admin what files am I unable to modify.

Hello,

If you are an "admin", you can modify any files in the system.

Login as the user, and try to run find with ! for that user with write permission.

[Muthukumar_5]

Use -user -group with ! to find files or directories which are not related to that user for writing.

If that is the case why does it keep saying access denied? I know you can modify anything as the "su" user but I have not got that access.

hi,

find is trying to check all the files and directories as per instruction.

Unless you are root user or equivalent, you will always get these messages.


have you looked into SUDO?

hope this helps!

kind regards

Hi
you can use this to look for file non writer by the user you are logged:

for FilNam in $(find . -type f 2>/dev/null) ;do
if [[ ! -w $FilNam ]]; then
echo file $FilNam not writeable
fi
done

HTH,
