How can I get diff in file content of current and previous revision number by command line?
And how can I get previous revision number?
回答1:
As per your comments you'd like to see differences between the current and previous versions of an item that is not in your working copy. For that you need to know the item's URL (e.g. svn://[repo_root]/[path]/[item]) which I assume you do. Then you do the following:
svn info <item-URL>
will contain (among other things) the last change revision. With that revision number R you run:
svn diff -c <R> <item-URL>
and it will give you the last commit diff.
回答2:
svn diff -r HEAD <item> if you want to get the difference between your working copy and the last committed revision.
svn diff -r PREV:COMMITTED <item> if you want to see what the last commit did.
You should take look at Revision Keywords.
svn info <item> will give you (among other things) the last change revision for the item.
