No, it *should not*, but it *does*, at least for me in an updated & dist-upgraded 32-bit version (up to date today).

I often use grep recursively, like this: $ grep -R somepattern * Since the upgrade from 15.04 to 15.10, it often happens that a lot of text files are wrongly treated as binary. That means that, when a match is found, instead of getting the normal output which would show the file name and the matching line (with the matching substring highlighted), I get the bogus message: binary file whatever.php matches Just to be clear: in one invocation of grep -R, I get mixed output with a lot of matches shown in the expected way and quit e a few matches shown in the wrong way, even though ALL matching files are text files. This worked as expected before the upgrade from 15.04 and 15.10. This is a HUGE issue that makes it impossible to do everyday developing work. Until you fix it, please f***ing roll back grep to the previous version, because this sh** is unusable.
