How do I change file permissions in Ubuntu

Question

In Ubuntu I want to change the file permissions of a whole folder and all its sub folders to read write by anybody  I have tried sudo chmod 666  var www and sudo chmod 755  var www without success  update  I have since found that changing privileges can also be done in the GUI by opening nautilus as sudo

Add -R for recursive   sudo chmod -R 666  var www

So that you don t mess up other permissions already on the file  use the flag    such as via  sudo chmod -R o rw  var www

User · Answer

If you just want to change file permissions  you want to be careful about using -R on chmod since it will change anything  files or folders  If you are doing a relative change  like adding write permission for everyone   you can do this   sudo chmod -R a w  var www   But if you want to use the literal permissions of read write  you may want to select files versus folders   sudo find  var www -type f -exec chmod 666          Which  by the way  for security reasons  I wouldn t recommend either of these    Or for folders   sudo find  var www -type d -exec chmod 755
