Re: [uug] Help with Regular expressions and backing up files

[Richard Miller]

OK, I stopped dragging my feet and started using rsync.  It looks like 
it will be exactly what I need.  And I haven't even experimented with 
remote syncing -- just a local copy that I will burn to CDs.  rsync, 
however, doesn't use grep matchings patterns, so I had to read the man 
to get it working with my exclusion list.

Thanks for the suggestion!

That flag (-v) was the trick that I had overlooked for grep.  Thanks!

Now as far as using that list of files to make backup copies, what
would be the best thing to do?
Consider using rsync, really.  It does all you want to do and more.  
And
it's very very fast.

All that comes to mind right now is a PHP script:

#!/usr/bin/php
<?php
        $fh = fopen("includelist.txt","r");
        while ($source = fgets($fh))
        {
                copy($source, $destination);   // needs error checking
        }
        fclose($fh);
?>

But PHP doesn't seem like the best thing for this.  What do you think?

	grep -v will do an invert match, only returning the files that don't
contain
the specified strings. You could then send that list to cp to make 
your
backups (make sure to use the -p flag to preserve permissions).
	But unison is a tool that will do exactly what you want. If you put
your list
of files in the ignore list in your preferences file, then unison 
will
never
touch them. unison has a lot of other features too, so perhaps it is
overkill
for your purposes.

I'm not a pro with Regular expressions, but I've learned that I can
type a command like this
$ find ~ | grep -f excludelist.txt

to show the all the files I want to exclude.

How do I, on the other hand, use the exclude list to show all of the
files I want to INCLUDE?
Actually, I don't know what I will do with a list of the files I 
want
to include, but there ought to be a way to backup those files once I
have a list.  Am I heading in the right direction?

Thanks!
