The commands are the same and it's still an Offline Defrag (meaning you have to dismount hte database) and you'll require atleast the size of the database and alittle more overhead free on the drive you are running it on.
Honestly if you have the space available, a much better alternative is to create an additional database, perform online moves to the new database and remove the old database. This will be completely online and seamless to the users.

why would you want to do that, you should have 175gb free at all times on your database drive.

The only way to shrink your mailbox is either by creating a new mailbox and then moving all the data from the old mailbox to the new mailbox or by defragmenting it. However, I do not recommend you to defragment the mailbox since it’s always quite a risky affair and it won’t make much of a difference since all that shall be removed are whitespaces which will be filled in anyway when Exchange server is deployed again. I strongly believe, Mailboxes are one thing you should avoid messing around with. Do not forget to make a fresh backup, as if you fail to do so the previous backup and the current one would not match.
You don't defrag jsut the mailbox, you defrag the entire database. Also, there's no reason to move all the mail to a newly created mailbox.

Eseutil is not intended as a maintenance tool. It's a repair tool. You should never run it unless you have a server crash and no backups and you are forced to run ESEUtil /P
Defrag has been automatic for years now:

Also, note that defrag doesn't shrink the side of the mailbox database in the filesystem. It coalesces whitespace within the file.
