count occurences of each word in novel David Copperfield

wget -q -O- | sed '1,419d' | tr "\n" " " | tr " " "\n" | perl -lpe 's/\W//g;$_=lc($_)' | grep "^[a-z]" | awk 'length > 1' | sort | uniq -c | awk '{print $2"\t"$1}'
This command might not be useful for most of us, I just wanted to share it to show power of command line. Download simple text version of novel David Copperfield from Poject Gutenberg and then generate a single column of words after which occurences of each word is counted by sort | uniq -c combination. This command removes numbers and single characters from count. I'm sure you can write a shorter version.
Sample Output
aback	1
abandon	6
abandoned	13
abase	1
abased	1
abashed	7
abated	1
abatement	1

?Is a joke? curl|awk -v RS='[^a-zA-Z0-9]' /./'{a[$1]++}END{for (i in a) print a[i], i|"sort -n"}'

I like the posted command better than the one by point_to_null. While point_to_null's is simpler and shorter, it does not strip out numbers and single characters. The download stats are nice, but not really an improvement.

@point_to_null: wow! i wouldn't imagine this can be done with as short command as yours. you must be a commandline guru..

Nice one! point_to_null gets points for doing it with fewer pipes. alperyilmaz gets points for using more tools though (in order: wget, sed, tr, tr, perl, grep, awk, sort, uniq, awk) showing people what piping really means.

...exactly. This doesn't make much sense. Any explanation why someone would want to count the words in this novel ?

@Alanceil something like this could be modified to find occurrences of words or letters following each other to create a Markov chain modeled after a given text. That would be useful for a text generator if you needed one...

tag clouds, semantic analysis, you know, stuff like that.

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
