Is it possible to change the write permissions on a file from inside emacs, without killing/re-opening the buffer?
Sometimes I forget to modify the permissions on a file before opening it. I can modify the permissions from inside emacs (
M-! chmod u+w filename) but this doesn't update the buffer which remains write protected and refuses to modify the file.
Is there a way to update permissions inside the buffer? Bonus point if I can assign this to a shortcut!
