To find the part to which I refer you'll need to scroll down about

Why does he echo hello, please?
Some greps (like BSD one) might not support '--color' option, so "echo
hello|grep --color=auto l" will return error code, skipping if clause,
and won't break grep operation by adding an unsupported option.
Ah! I see! Many thanks!
