Finding the revision of a deleted file.
I have been doing some work everyone's good friend Mr.Google.
Every blog / article I read all said the same thing;
Create a file with svn log
(svn log --verbose > svn.log)
Then grep / search the log for the file you're after.
It takes about 8 minutes just for the log file to be created - which makes it a slightly painful workflow - just to resurrect an old file.
Is there not a more convenient way to do this?
As always thanks in advance.

If you do not know the path to the file, then I think
svn ls --depth=infinity
together with peg revision set in the past will help you to locate it.
Then you can use svn log on the file to see when it was deleted and
svn cp it from any revision before that.

It's always the way ....
I should have been a little more clearer about my requirements.
I have a file; fileName.txt
This file exists "somewhere" in the repository at a previous revision because it was deleted at sometime in the past.
So, I am unable to restrict the path that svn.log starts at.
I can't think of a way to do it other than the svn log method...
And the fact that Mr.Google has only revealed the svn log method, too - I assume there simply isn't a better method...
It just seems like there "should" be an easier method - so I figured I had better ask as opposed die wondering...

I guess you are "log"'ing a lot more than necessary. Have you looked
at the options available for the log command? I use the "--limit" one
very often. Are you calling this command for the right path?

Firstly, let me thank everyone for their help.
I was "hoping / wishing" that here was some simple command line instruction(s), that I simply didn't know about, that would do the job for me.
It would appear, not in the way I had hoped.
Mark Cooke suggested that I use a hook script to maintain the log every update, that way all I ever had to do was grep and not the log creation too.
Which is an excellent idea, and seems to be inline with the earlier suggestion of Stefan's of using "svnsearch" or "fisheye" for the task.
It was more a case of working out if I "could" do what I want internally within subversion, or whether Google was correct and I had to use one of the processes that have now been mentioned here.
Slightly different but I only just found out that you can use svn merge to obtain a list of changes that an svn update will do to your working copy.
svn merge --dry-run -r BASE:HEAD .
which in effect is a svn update with a --dry-run switch.
So I just wanted to make sure something like that didn't already exist for me to find out a deleted revision / path of a long lost file.
Thank you everyone for your considered responses - I do appreciate the time you've taken to help me out.

...just my 2€: having created the log file once, could it not be "maintained" using a post-commit hook script and appropriate arguments, then you eliminate the need to recreate the log file each time and just have the 'grep' stage...

Hi Stefan / Konstantin,
Thanks for the responses.
The data mining tool looks promising, and as you state, allows for some "extra" goodness too.
Gavin.

Hi Gavin,
this thread had some interesting technical discussion about this topic:
http://svn.haxx.se/users/archive-2010-11/0509.shtml
One way to work around this limitation is to use a data-mining tool which
crawls the repository and fills a relational database with information.
This DB can then be queried, often via a web interface. Two such products
are "svnsearch" (open source) and "fisheye" (proprietary).
They do more than just locating deleted files, though. I think both support
full text search of file content of all revisions in the repository, too.
