Checking permissions of files under a folder

TravisBrooker · 03-25-2021, 05:52 AM

Dear all,
i would like to put a script to check permissions,
if the file permission is only rw i want to receive an e-mail.
rw means 600,
i did something like that but it only checks folders, not the files under the folder.

#!/bin/sh
PERM=600
PARENT=/.../folder
folders=$(find $PARENT -type d ! -perm $PERM)
if [ -n "$folders" ]
then
echo "$folders" | mailx -s "smt wrong in permission" abc@xzy.com
fi

what should i do? thank you in advance.

That's because it is using -type d to select only the directories. You can check the files separately using -type f

As mentioned by Turbocapitalist, you have "-type d" which only checks directories.
Another issue I see is the "!" which is logical NOT.

For troubleshooting, breakup your tasks in 2. First just focus on the find... Once you have find working then add the notification piece...

Change this line you script

Code:

folders=$(find $PARENT -type d ! -perm $PERM)

to

Code:

folders=$(find $PARENT -perm $PERM)

Run it again, does it work?

sudo (file manager) permissions tab
Do whatever you want in there
sudo thunar
password
opens file manager as root
permissions
GO

I'd do it like this

Code:

find -perm 600 -exec sh -c 'printf %s\\n "$@"|mail -s "wrong perm" me@host.com' _ {} +
