How to enables special charaters

[slyexe]

It wouldn't be necessary but if you are unsure of your password length you can use increment to test all lengths based on your mask length. 

For example

hashcat -m 0 -i -1 =-09876\][poiuy hash.txt ?1?1?1?1?1?1?1?1?1?1

would try all mask length from 1-10 rather then just a single attack vrs 10 characters.
