How to make SVN perform a command without making changes

Question

In CVS I could do the following

cvs -n update

And it would should me what would happen if I ran an update but without changing anything. I mainly use this to check if I am going to get a lot of conflicts.

In svn I would like to do the same but with the switch command

ie:

svn -n switch url1 url2

My understanding is that there is a --dry-run switch which goes through the motions but doesn't actually give any output. So it is half of the way there :)

How can I get it to do a dry run and show what the results would be (which files will be Modified, which Updated, Deleted, Added and Conflicting).

Thanks

Update: Regarding those who have suggested I use --dry-run I have tried the following

svn switch url --dry-run

and I get

Subcommand 'switch' doesn't accept option '--dry-run'

In theory it sounds good but it doesn't seem to work, am I doing something wrong?

Answer 1

Use merge and --dry-run with the same URLs you will use for the switch. It should give you the information you are looking for even though you'll be using switch instead of merge in the end.

Answer 2

On svn update, you can use svn status --show-updates to show all items you will update.

For merges, you can use --dry-run any problems.
