I copied a set of BlueJ files from
/usr/share/doc/BlueJ to a
~/BlueJ directory however the files in folders are set to root permission and read only I need to be able to read/write them.
So in BlueJ folder there are sub folders for each project for example 'shapes' folder.
I found this command here for changing a singular file File Permissions Ubuntu
user@host:/home/user$ sudo chmod o+x /usr/local/bin/somefile
But how can I change the folder permissions and subsequently all files in folders for every project folder in
