Newbie need help

[tysus2002]

Hi, I'm new in hashcat. I need some help here, hope someone can help me with this and thanks so much!!

For example: The password is Longgone8384!

Condition: 
I don't know the exact password.
I know the password contains l,o,n,g,e,8,3,4,!
I forgot the password length.
I forgot the capital letter and lower case.

Question：
I want to hash the password with L,o,n,g,e,8,3,4,! only, so it won't waste the time go through all other alphabet and numbers.

If I use Brute force attack mode with ?a Charset it will take so long time to hash.

Can I edit the Charset? How？

May I know which attack mode should I use and how？ If you can provide me the exact command to use that will be great.

hashcat -a 3 -m hashtypenr -i -1 longe834! hashfile ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1

It crackes, exhaust or might run out of keyspace on longer passwords.

sorry if it was uppercase l then change it Longe834!

if other letters could also be upper you have to change to

-1 lLoOnNgGeE834!

in this case a maskfile would be my chioce, because it could be, that some cli have problems with special chars like ! in the prompt
