I opened a text file from a remote server, edited it and saved it. The transfer "failed" because I didn't have sufficient permissions. Indeed, I didn't -- I was in the group, but no write permissions, so I ssh'd in and chmod g+w, and tried saving again. Got the same "permission denied" error, but back in the terminal, I did 'ls -l' and saw that the file now had size 0. I had to chown the file and save again before it would work.
