Finding (and fixing) files with undesirable permissions

I use a few programs that create files that are not group read/writable; this is an issue when working in a group environment (especially with Knime where important files are locked this way which prevents other users from even opening your workspaces). Here's a find command that'll locate these files:

find . ! -perm /g+r -exec ls -lh {} \;

This command executes 'ls -lh' on each of the files to show the current permissions (would probably be more efficient to push into xargs to run ls on multiple files at once). The next find command will update the permissions on those files:

find . ! -perm /g+rw -exec chmod g+rw {} \;

Of course, you can just run chmod recursively (chmod -R g+rw *), but this isn't always what you want.
