The guy asked for unix command

Sir, I think,
There is no such command to do that, He can compile this code and create his own command.

I think we can use mix of sed or fold and echo something like
$ echo "QUERYHOME" | sed -e 's/\(.\)/\1 /g' | tr ' ' '\n'
$ echo "QUERYHOME" | fold -w 1

This works perfect on command-line..
