Actually, you do get permission denied every time you try to write to a file that you don't have write access to. Some editors, however, will change the file's write-permission bit so it can be written, write it, then change the write-permission-bit back. Incidentally, there are 4 read/write states a file can be in for each of the 3 sets of owner, group, and other: read/write read-only write-only neither That is, the readability of a file is completely independant of the writeablity of a file.
