Error in syntax?

[aleff-github]

Hi i'm trying to use your tool but i don't understand what is the problem.
I send it
gobuster dir -u https://10.10.175.13/ -w ~/wordlists/shortlist.txt

and I have this error
2021/04/21 15:27:00 [!] 2 errors occurred: * WordList (-w): Must be specified (use '-w -' for stdin) * Url/Domain (-u): Must be specified

But if i try just this below works
gobuster -u https://10.10.175.13/ -w ~/wordlists/shortlist.txt

you are using an old version of gobuster. Be sure to update to the latest version to use the new gobuster dir syntax
