I only wanted to change the permissions of a folder which contains a lot of other folders and files, but ended up changing everything from root ( / ).

I searched for "change permissions of all files and subdirectories linux" and ended up finding this: How to set chmod for a folder and all of its subfolders and files in Linux Ubuntu Terminal? [closed]. I used the code which had the top upvotes, except that I removed the path because I thought I didn't need it because I was already in the folder I wanted to change. What I didn't think through, was the little forward slash I put in there, so everything changed to 777

find / -type d -exec chmod 777 {} \;

Now I can't access it with ssh or sftp. What should I do to change the permissions back again?

  • restore from backup, or
  • reinstall.
