script to scan /home for folders with 777 permission
 

Hello

How can I prepare a script which will scan /home for folders with 777 permission and then it will set 755 permissions on those folders.

command find /home/ -type d -perm 777

will scan the /home for folders with 777 permission, but know I need to set 755 permission on this folders.

Please help in resolving this issue.

Thank you

Regards!

This sounds a little like homework, but have a look at 'man find'. Specifically, you can search for files with certain permissions with 'find [directory] -perm [permissions]'. Then use the '-exec' construct in find to convert the permissions.

Hi

The following command will find the folders with 777 permission

find /home/ -type d -perm 777

but I need know to set permission 755 on the folders which are found after executing the above command.

I am quite new to scripting, Please if anyone can help in getting to the point.

Look at the man page again and read the section on exec.

Or use a loop
see http://tldp.org/LDP/Bash-Beginners-G...tml/index.html and man page for chmod

You can also pipe to xargs:

EDIT:
see my post below for fixing whitespace

I wouldn't do as suggested by chrism01 and H_TeXMeX_H. It's asking for trouble because of paths with spaces inside. I'd rather do

find … -print | while read path; do … ; done

or (if I need to be able to modify the current environment):

while read path; do … ; done < <(find … -print)

But then, of course, neither is needed in this case. As said before, look for the '-exec' option in find man page; there's not much to it und it's the answer.

Oh, good point, here's a good way to fix white space issues:

Or find all that aren't the right permissions and change them.
