On Debian 12, /bin/echo (which is from GNU coreutils) and bash's builtin echo do not share the same feature set: hobbit:~$ /bin/echo -e '\u0061' \u0061 hobbit:~$ echo -e '\u0061' a As was pointed out earlier, builtin printf and /usr/bin/printf also have different features (%(fmt)T being one of them). Having two different printfs, and two or more different echos, has ALWAYS been the case on non-GNU-based systems (commercial Unix, BSD, etc.) where bash is being used. If the world weren't so narrowly "Windows, Mac and Linux" nowadays, perhaps people would remember the diversity of operating systems a little better.
