Cut a large wordlist into smaller chunks

less file.lst | head -n 50000 > output.txt
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.

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.
