Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

computes the most frequent used words of a text file

using

cat WAR_AND_PEACE_By_LeoTolstoi.txt | tr -cs "[:alnum:]" "\n"| tr "[:lower:]" "[:upper:]" | sort -S16M | uniq -c |sort -nr | cat -n | head -n 30

("sort -S1G" - Linux/GNU sort only) will also do the job but as some drawbacks (caused by space/time complexity of sorting) for bigger files...

Alternatives

There are 3 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

i think there's database of most common used words in English, so we can remove those words from this list and see the frequently used words specifically by Tolstoi

Very similar to my own script: http://l0b0.wordpress.com/2010/05/31/tag-cloud-shell-script/

Comment by l0b0 264 weeks and 5 days ago

The awk part is needlessly complicated. You can use "uniq -c" for that.

Comment by inof 264 weeks and 4 days ago

uniq -c can not do this! have a look in my description.
