you are still using window$?

Hello,
Actually I used the vi editor to modify the file. When I use touch command or cat >> example the creation time does not change.
But why should this happen? This behaviour is not seen with Windows.
Thanks,

It seems the bash builtin echo modifies the file whereas vim (probably) performs the safer operation of writing a temporary file and then using rename(2) to replace the file.
