Before I would write "sudo chmod 777" and then the name of the file or folder but now it doesn't seem to change any permissions. I looked at multiple tutorials on how to use chmod and can't figure anything out. I need to change permissions of a folder with a lot of files. How can I change the permissions of all the files in one go? I need to change the permissions from root to my user account. Running nautilus in gksudo only allows me to change the permissions 1 file by one which will take way to long to do. When I select multiple files at once and go to the permissions tab in the properties it just says that the owner is root and I cannot change it.
