Wordlist Filter

This script filters a wordlist by word length, presence of digits, and symbols, and removes duplicates.

Usage

./wordlist_filter.sh wordlist.txt [min_length] [max_length] [--no-digits] [--no-symbols]

• wordlist.txt — input wordlist file (required)
• min_length — minimum word length (default: 1)
• max_length — maximum word length (default: 100)
• --no-digits — exclude words containing digits
• --no-symbols — exclude words containing symbols (keep only letters and digits)

Examples

Keep only words with length from 6 to 12:

./wordlist_filter.sh rockyou.txt 6 12

Keep only words without digits:

./wordlist_filter.sh rockyou.txt --no-digits

Keep only words without digits and symbols:

./wordlist_filter.sh rockyou.txt --no-digits --no-symbols

Output

The result is saved to
filtered_<your_input_file>.txt
in the same directory as the script.

• Utilities: awk, grep, sort, uniq
