Interestingly, OS behaviour differs on precedence of -i and -f. AIX
for example, -f does not override a -i whereas on GNU implementations
of rm, -f overrides -i. This has led me to give more credence to not
aliasing rm or cp or mv to their -i equivalents since the order of
precedence is not standardised.
Be warned when working across multiple Unix and -like variants.
