I was trying to chown within /opt and for some reason chown jumped up to the parent and chowned everything.

Can anyone suggest why/how this might happen, and how to avoid doing it in future? It's a bit concerning that running a command in a given dir can effectively jump up and run it in root dir.

i'm new to Ubuntu and was wondering if there is a way to remove the ownership of all files and scripts from root to user even if i have to re-install Ubuntu? i do know about the command 'chown -v username foldername', although it doesn't work on all files.

I ran the chown command in a directory:

chown -R user:user {.,}*

The {.,}* is used with mv and cp to include both hidden and listed files. Now this command went through and changed those two files in my directory, but I had to break it to stop since it went on. Now I'm afraid it has gone and changed the permissions on other files and folders, since it didn't terminate.

I am using Ubuntu 13.04 VPS and have installed LAMP (apache2). Now I have uploaded my web files (WordPress) in /var/www. But I dont have permissions to write in files.

When I run WordPress install, it says that it could not write on wp-config php file. So I execute this command over SSH

su
cd /var/www
sudo chown www-data:www-data -R *
/etc/init.d/apache2 restart

(www-data is my apache user).Still itv cant write into files. I also cannot upload files using FTP (transfer failed error).

The permissions for directories in /var/www are 755 and for files are 644. Setting permissions 777 resolves the problem but I dont want to CHMOD it 777.

Please help me out.. Thx.
