Got it.

Solution is
if echo "$word" | grep −q "$letter_sequence"

It was there in the Advanced Bash scripting guide. It can be found at http://www.tldp.org/LDP/abs/abs-guide.pdf

Thanks Perderabo
Thanks zazzybob.

That is not a great solution. It doesn't make sense to invoke an external program to do what bash can do internally...

if [[ $var = *k* ]] ; then echo yes ; fi

will test var for the presence of a "k".
