Retrive the permissions

[Anoop Sivan]

Hi All

Is it possible take permissions back-up of all the files under the directory in octal format before running the chmod in recursive mode.

Have you looked at my scripts? They don't use the obsolescent octal format but use a symbolic format, which is the preferred format for chmod(1).

- permission backup you can take with just:

#DATE="`date +%H%M.%m%d%y`" ; DIR="/oracle_pub"
# find $DIR -xdev -exec ls -l {} \; > all_file_dir_details.$DATE.txt


- The .txt file can be followed anytime you have problem finding any file/directory permission or ownership problem. And you can set it with chown and chmod command.


Cheers,
Raj.

Yes but you really want a script to handle the zillions of bad files.

>find ... -exec ls -l {} \;

By using "+" instead of "\;" you can make it much faster. And you need to add "-d" so you don't list files twice:
-exec ls -l -d {} +

Dennis, Thats very true ,. thanks! for the tips.. {} + , is wonderful , and executes so fast. Never tried before.
And ofcourse a script can only help to fix zillions of files..,

Regards,
Raj.

Anoop, (again),
Check out the script attached to save current permisions in both numeric and -rwx format.

Anoop, (again),
Check out the script (getperms) attached here ,to display/save current permisions in both octal and -rwx format.
