The pre-commit hook will get two input parameters. The first is the 
repostiory path, the second is the transaciton ID. 
You need to pass this to svnlook: 
svnlook diff c:\somerepository --transaction sometransactionId
This will allow you to watch the commit that's begin executed. 
Have a look at the manual: 
http://svnbook.red-bean.com/nightly/en/index.html In this case you need 
http://svnbook.red-bean.com/nightly/en/svn.reposadmin.maint.html#svn.reposadmin.maint.tk.svnlook
 
 but if you have not yet read the entire manual, you really should, it 
will save you a lot of time and headaches!
