RE: How find GNUAPL svn repository revision number

[Callahan, Brian Robert]

In your script, you could use wget or curl or lynx to download that web page, then pipe it into some creative use of grep/sed/awk/perl to extract just the title, then another pipe to another round of grep/sed/awk/perl to get just the revision number.

Untested, but something like this should be close to working:

lynx -dump http://svn.savannah.gnu.org/svn/apl/trunk/ | sed '2q;d' | awk '{ print $3 }'

You might have to play around with the sed or the awk column or something, but this should be a good first step.

Thanks for your reply but I don’t understand what you mean by ‘scrape that’

Will be in the page title. I'd say scrape that since it's easy to do so.

Subject: How find GNUAPL svn repository revision number

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
