yossarian (1.3.6.1.4.1.55738)TIL: Some surprising code execution sources in bash

Kees Cook (old account)@yossarian The use of '[[' is the problem. That's an evaluating comparison and is as dangerous as 'eval' (as shown). All scripts should be using just the single '['. Using '[[' is for compatibility with ancient shells.
gunstick@kees @yossarian I tried with [ and it did not work. And 'type [' says "shell builtin" whereas 'type [[' says "shell keyword"
