How do I change filepermission for all .jpg images, folders and subfolders?

I want to change to 0777 for a short period while a script make some changes (some images have different owners) and then back to normal again.

After the script is finished I want all folders to be 0755 and all .jpg images to be 0644.

Code:

find /path/to/dir -name "*.jpg" -or -type d -print|xargs chmod 777

reverse

Code:

find /path/to/dir -name "*.jpg" -print|xargs chmod 0644

find /path/to/dor -type d -print |xargs chmod 0755

Thanks,

Never seen it like this before. Can you explain how it's working?

I assume you've seen stuff like:

Code:

chmod -R 777 /path/to/dir

which for your 1st phase would work fine (except that it would chmod everything to 777 not just jpg's and directories).

To reverse it you can't run a recursive chmod because you need different
chmod for files and directories

Code:

find /path/to/dir -name "*.jpg" -print

finds all images in that directory and prints them
xargs executes "chmod 0644" for each image
