1 yum install -y subversion (download svn)
2 svn chekout "your svn address"
Then ask? I don't know what it means. It's basically a mess of permissions. Anyway, you enter a "p" and press Enter, then enter your username and password and you're done.
3 svn update with new code,
4 svn resolved resolve conflicts,
I don't use other commands often, generally no one will write code on linux, right?
