Wordlist Manipulation
Password file merge, sort by unique entries:
Sorts all files in a directory
Copy find . -maxdepth 1 -type f ! -name " .* " -exec cat {} + | sort -u -o $out_file https://unix.stackexchange.com/questions/365114/efficiently-merge-sort-unique-large-number-of-text-filesarrow-up-right
Remove the space character with sed
# sed -i 's/ //g' file.txt OR # egrep -v "^[[:space:]]*$" file.txt
Remove the last space character with sed
# sed -i s/.$// file.txt
Sorting Wordlists by Length
# awk '{print length, $0}' rockyou.txt | sort -n | cut -d " " -f2- > rockyou_length-list.txt
Convert uppercase to lowercase and the opposite
Remove blank lines with sed
Remove a specific character with sed
Delete all instances of a string with sed
Replace characters with tr
# tr '@' '#' < emails.txt OR # sed 's/@/#' file.txt
Print specific columns with awk or cut
# awk -F "," '{print $3}' infile.csv > outfile.csv OR # cut -d "," -f 3 infile.csv > outfile.csv
Note: if you want to isolate all columns after column 3 put a - (dash) after the number: # cut -d "," -f 3- infile.csv > outfile.csv
Generate Random Passwords with /dev/urandom
Remove Parenthesis with tr
# tr -d '()' < in_file > out_file
Generate wordlists from your file names
# ls -A | sed 's/regexp/& /g'
Process text files when cat is unable to handle strange characters
# sed 's/([[:alnum:]]*)[[:space:]]*(.)(..*)/12/' *.txt
Generate length based wordlists with awk
# awk 'length == 10' file.txt > 10-length.txt
Merge two different txt files
# paste -d' ' file1.txt file2.txt > new-file.txt
# export alias sort='sort --parallel=<number_of_cpu_cores> -S <amount_of_memory>G ' && export LC_ALL='C' && cat file.txt | sort -u > new-file.txt
# tr '\015' '\012' < in_file > out_file
# dos2unix file.txt
# unix2dos file.txt
Extract the difference between two files
# grep -F -v -f file1.txt -w file2.txt > file3.txt
Isolate specific line numbers with sed
# sed -n '1,100p' test.file > file.out
Create Wordlists from PDF files
# pdftotext file.pdf file.txt
Find the line number of a string inside a file
# awk '{ print NR, $0 }' file.txt | grep "string-to-grep"
Create your own Dictionaries
Find as much information about the target as you can and generate a custom dictionary. Tools that may help:
Create a wordlist with lengths from 4 to 6 using a specified character set
Create a list of 4 character "words" using the character set mixalpha (inside file charset.lst)
Character set examples:
Using this you can make wordlists using custom character sets with shortcuts
Generate a wordlist based on a target website
Generate passwords based on your knowledge of the victim (names, significant dates, etc...)
