My interpretation, without knowing what Operating System we have here or what Shell the O/P uses or anything about the mounted filesystems.

Code:
find /home/ -xdev -type d -name "log" -print | while read dir
do
        ls -lad "${dir}"    # before
        # Remove echo when tested
        echo chmod 755 "${dir}"
        ls -lad "${dir}"    # after
done

This one is one-shot:

Code:
 
#chmod -R 755 <dir_name>

That is madness. I trust that the O/P will ignore this post.

I don't think it does.

Illustration:

I have a directory dir3 and it has some sub directories and files. What I'm trying to do is assign same permissions for that dir3 and its contents (say 777).

--> Before chmod (actual permissions):
Code:
 
# ls -ld dir3
drwxr-xr-x   4 root     root         512 Feb 16 16:34 dir3
# ls -l dir3
total 4
-rw-r--r--   1 root     root           0 Feb 16 16:34 f1
drwxr-xr-x   2 root     root         512 Feb 16 16:34 f2
-rw-r--r--   1 root     root           0 Feb 16 16:34 f3
drwxr-xr-x   2 root     root         512 Feb 16 16:34 f4
-rw-r--r--   1 root     root           0 Feb 16 16:34 f5

--> After my madness:
Code:
# chmod -R 777 dir3
# ls -ld dir3
drwxrwxrwx   4 root     root         512 Feb 16 16:34 dir3
# ls -l dir3
total 4
-rwxrwxrwx   1 root     root           0 Feb 16 16:34 f1
drwxrwxrwx   2 root     root         512 Feb 16 16:34 f2
-rwxrwxrwx   1 root     root           0 Feb 16 16:34 f3
drwxrwxrwx   2 root     root         512 Feb 16 16:34 f4
-rwxrwxrwx   1 root     root           0 Feb 16 16:34 f5

@satish51392111 and what has this to do with this thread?

Omg chmod -R 777 . There is never ever a reason to issue this sort of idiot command.

Permissions 777 is a security nightmare. My advice to all reading this thread is don't do it.

If I was your boss, I would remove your admin rights permanently.
