- Well, you can make this error in other operating systems too, here's VMS:
- $ define SYS$OUTPUT myfile
- $ type myfile,anotherfile
-
- Of course, VMS keeps every version of every file I have ever made
- (assuming I'm a naive user who haven't heard of purge), but then
- I probably won't know how to get the old version back, either.
-
- Probably ANY decent OS/UI will make it possible to make exactly this
- mistake. To put it another way: If you add features to make it
- impossible to make this kind of mistake, it won't be a good OS/UI
- anymore.
-
- It's just that it is much easier to do it in Unix. Remember: Unix
- was designed to make it possible to do smart things easily, it was
- NOT designed to make it hard to do dumb things.
-
- I can imagine it will be impossible to make this mistake in
- Windows/NT, but I fully expect that it will be impossible to
- concatenate two files in Windows/NT too.
