RE: How can I parse the output of "svn update"? [SOLVED]

Touché

You are correct in that YOU were a kind soul to help and for that I am
grateful. Since your email didn't have any indication in the subject that
this was from the subversion list, I mistakenly thought you were from the
svlug list for some reason.

And while I sort of see your point, I think it's a little short sighted (no
offense intended). The question I posed *is* related to subversion AND shell
scripting... (Most tools do not exist in a vacuum and in fact all the
pre/post commit scripts require a scripting language to use them)

This is a problem that I would think is not unique to our development
environment, and one that would be nice if subversion had built in hooks to
handle somehow. I think it is fairly common for developers to have to update
a SQL database or do some other task (such as clear a Symfony cache if the
routing.yml file changes), or any number of other "trigger this
message/script if this file is changed" scenarios.

There are all kinds of pre-commit and post-commit scripts, but this pain
falls in a different realm -- that of "svn update", for which there doesn't
seem to be any kind of hooks (of course because SVN resides server-side and
'update' is client-side). However, one still needs to install the subversion
package on any *nix box and therefore the solution/scripts could be included
as wrappers or triggers to the "svn update" command. I'm sure tigris could
work some magic within the ~/.subversion directory to trigger an external
script on update.

Anyways... thanks for your reply and I hope that my posting will help some
other developer trying to accomplish this task.

Not entirely true:

I sent you a private response which included an outline of a shell
script that would do what you want.

I didn't send the response to the list because it had nothing to do
with Subversion. The question you asked had more to do with shell
scripting or in your case AWK.
