文件权限问题javac

Question

I have files in a directory. Some have root as the owner and group and some user (me) as owner and group (however that happened). I ran sudo chmod 755 -R /usr/casloader , all my directories are under /usr/casloader . All files are -rwxr-xr-x .

I am trying to compile a java class (as me the user) - if run the javac on a file that owner/group is root , I can compile fine. The owner/group of the compiled class becomes me. (it writes the compiled class into the same folder).

But if I try compile a class that owner group is me it gives file write error: Permission Denied .

How do I solve this? Does everything have to be root?

Answer 1

I just did g+w,o+w with a -R. so I have rwxrwxrwx - so the problem is solved. (Not sure if this is the most optimal solution.)
