A question about Subversion and commit from the command line

Hey guys, so I want to start using the terminal when I do thinks like update, commit and whatnot. I am use to using kdesvn which is a GUI that helps me with subversion. However, kdesvn does not seem to play well on 18.04 and regardless I am trying to move away from GUI's in general. I want to commit some changes to a branch but I want to be sure that I get a report of the changes prior to the actual commit. In other words, what I want to know is if I use this command for my commit:

svn commit -m "Update script from py2 too py3."

will it allow me to review the changes being committed? If not, how can I go about committing in such a way that it will first show me what I am about to commit (what scripts have changes) and then ask me if I am sure I want to commit?

Perhaps I should be saying:

svn commit -m "Update script from py2 too py3." script.suffix

which would work but doesn't give me the functionality I was hoping for. Perhaps the functionality I am hoping for simply doesn't exist?

Maybe you can consider GIT.

I use GIT and really like it
