egrep -ci ^[aoeuidhtns-]+$ /usr/share/dict/words

Show the power of the home row on the Dvorak Keyboard layout

Quick and dirty command that counts how many words can be typed just using the home row on the Dvorak Simplified Keyboard layout from a dictionary file, in this case /usr/share/dict/words. According to the regular expression supplied, each word must contain all the keys on the Dvorak home row, and no other characters. For comparison, I've shown how many words are installed in my dictionary, how many can be typed with just the Dvorak home row and how many can be typed with just the QWERTY home row in the sample output. Nearly 10 times the amount. If you want to see the words, remove the -c switch, and each word will be printed out.
Sample Output
$ wc -l /usr/share/dict/words
98569 /usr/share/dict/words
$ egrep -ci "^[aoeuidhtns-]+$" /usr/share/dict/words
1969
$ egrep -ci "^[asdfghjkl\;\']+$" /usr/share/dict/words
233
