They both have subdirectories called uploads. /home/jim/uploads is owned by jim in the jim group and has protection mask 755 (drwx-rx-rx). /home/bob/uploads is owned by bob but in another group entirely, and its protection mask is 774 (rwxrwxr--). I want to change /home/jim/uploads to the same permissions as /home/bob/uploads, but whenever I "sudo chmod +g /home/jim/uploads", nothing happens.

Never mind, I figured out what I was doing wrong. The proper command is:


chmod g+w uploads


*NOT*


chmod +g uploads


Yes, it's chmod that does the job.
