Using large wordlists is cumbersome. Using password cracking programs with rules such as Hashcat or John the ripper is much more effective. In order to do this many times we need to "clean" a wordlist removing all numbers, special characters, spaces, whitespace and other garbage. This command will covert a entire wordlist to all lowercase with no garbage.

Take a file and ,."()?!;: give a list of all the words in order of increasing length. First of all use tr to map all alphabetic characters to lower case and also strip out any puntuation. A-Z become a-z ,."()?!;: all become \n (newline) I've ignored - (hyphen) and ' (apostrophe) because they occur in words. Next use bash to print the length ${#w} and the word Finally sort the list numerically (sort -n) and remove any duplicates (sort -u). Note: sort -nu performs strangely on this list. It outputs one word per length. Show Sample Output
0for w in $(tr 'A-Z ,."()?!;:' 'a-z\n' < sample.txt); do echo ${#w} $w; done | sort -u | sort -n -
usage: dng BRE [selection] default selection is the last match DNS is ok, but although domainnames may be easier to remember than IP numbers, it still requires typing them out. This can be error-prone. Even more so than typing IPv4 numbers, depending on the domainname, its length and complexity.
0dng(){ local a;a=$(sed '/'"$1"'/!d' /etc/hosts |sed '=;'"${2-1,$}"'!d'|sed '/ /!d');echo $a|tr '\040' '\n'|nl -bp'[0-9]$'|less -E;export dn=$(echo $a|sed 's,.* ,,');export ip=$(echo $a|sed 's, .*,,');echo \$dn=$dn;echo \$ip=$ip;} -
