How find GNUAPL svn repository revision number

[Peter Teeson]

I’ve searched and read for the answer but come up dry.

I’m on macOS High Sierra

Assume I have svn co'd …trunk to a local working copy

I want to write a bash script to 

    compare the local working copy revision number 

vs 

   the svn://svn.savannah.gnu.org/apl/trun repository revision number.

I know how to find out the revision number of my local working copy

using svnversion or svn info if i need more data.

My question: 

But I don’t know how to script to get the revision number 

of the svn://svn.savannah.gnu.org/apl/trun

Please help….

Thanks

Peter
