Syntax:

crunch [min] [max] [characters] -o [filename]

min: Define integer saying a minimum number of characters in a word.
max: Define integer saying a maximum number of characters in a word.
characters: Define characters that will be used to create all the combinations with that words, under the defined minimum and maximum length.
filename: Define the name of the file which will be your output file name followed by .txt.

For Example, create a wordlist using the letters which can be used to create a word hackhunt with all the possible combination with a minimum of 8 letters and a maximum of 10 letters and save it to a file name wordlist.txt.

crunch 8 10 hkcantu -o wordlist.txt

If you want to create all the possible combinations with certain patterns, you can add -t [pattern].
For example, create a wordlist with all the possible mobile numbers (10-digit) starting from 9 and save it to a wordlist.txt (this wordlist can be used to hack Wi-Fi, as most Indians have some kind of mobile numbers as Wi-Fi Password and most of them start from 9)
