Error running hashcat commands

Ive recently downloaded the latest version of hashcat from github, and am not trying to run a basic bruteforce attach on the sample hashes provided.

However, despite reading the documentation I consistently get the following error, where ?a?a?a is changeable to the type of option I provide (And have no idea where Im going wrong):

For example the following command: 

hashcat -a3 example0.hash ?a?a?a

Returns this: 

zsh: no matches found: ?a?a?a

If I changed ?a?a?a with ?l?l, then the error would change to include this new parameter.

Ive tried many different variations to no avail. Any insight is appreciated. Thanks!

Worked for me to put the mask in quotes, e.g.: hashcat -m 1800 -a 3 -o ans.txt Target-Password.txt "?u?l?d?d?d?d"

You seem to have a couple things missing:

the -a3 is a mask attack. to do what I think you're trying to do and specify a mask on the command line, you need to define the charset after the -a 3 ie: -a 3 -1 ?a

Then, you'll need to specify the hash type with -m

Then lastly, you'll need to specify your mask. So assuming the examples are ntlm, your command would look like:

hashcat64.exe -a 3 -1 ?a -m 1000 example0.hash ?1?1?1

It's thick reading, but the wiki is indispensable: https://hashcat.net/wiki/

?a?a?a is not a valid command.

Remove it and try, if that doesn't work then you should probably be specifying a -m so Hashcat knows which hash type it is. Also -a0 is important for brute force attack mode. Remember Hashcat have their own community forums where you will get more in-depth answers as I am not too experienced with the tool.

Open CMD in correct location and:

$ hashcat64.exe -a0 -m0 example0.hash

Remember not to include '?a?a?a' as that is not a valid input for Hashcat, not sure where you found it.
