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.

Cut a large wordlist into smaller chunks

Useful for situations where you have word lists or dictionaries that range from hundreds of megabytes to several gigabytes in size. Replace file.lst with your wordlist, replace 50000 with however many lines you want the resulting list to be in total. The result will be redirected to output.txt in the current working directory. It may be helpful to run wc -l file.lst to find out how many lines the word list is first, then divide that in half to figure out what value to put for the head -n part of the command.

Know a better way?

If you can do better, submit your command here.

What others think

Could skip the 'less'. Not harmful but wastes a process:

head -n 50000 file.lst > output.txt

Might also consider trying 'split' instead:

split -l 50000 file.lst output.txt.

very true. Never used the split command before, thanks for the heads up tho.
