Hehe, you know what makes the software more complex to use? Having to grep in the output of "grep --version" before deciding which switch to pass to grep.. :)


You don't need to do that, just always use -R :)


We'll get right on inventing that time machine so everyone can go back in time to the introduction of the -r flag and warn themselves ;).


And note that it will make your code more compatible with other, POSIX-compliant, versions of grep.
