Yea, it seem's possible to do it with others utilities included in /bin
or in /usr/bin as well.

Sorry, my fault. I was in a rush for doing sometime elses and that time
and I must admit that "the grep solution (tm)" is not so sporty for a
task like this.

However, constructive criticism is always welcomed, and as you noted,
the logic was not valid for that specific situation.
