ghenry you are really into perl now are you :)

Where did you learn perl skills?
And how come you like perl so much?

I'm thinking of learning perl too...

[ghenry]

I just bought Learning Perl and bought the Perl CD Bookshelf from ebay.

Joined the beginners perl mailing list and went from there.

I love it because you can do so much with it and as it is quite hard it really makes you think about your filesystem etc. and things can easily be applied to php and others.

It is the swiss army knife, as there are so many modules.

My next project is going to be using http://axkit.org/, like www.gentoo.org as I love the structure of xml and like docbook xml too.

Also, at my day job I have some graduate engineer things to write up, so I am writing a script to pull things from google and write them to openoffice writer, so I don't have to keep copying and pasting :-)

Gavin.

Would you like a free copy of Perl CD bookshelf as a favour? You can have my official backup copy :-)

No copyright infringement then :-)

You would do that?
I'd really like to learn more about perl...

This is a CD right? How would I get it?

[ghenry]

I have made a bzip2 tarball of the CD, it's basically, 7 O'reilly Perl books in HTML with a java search feature:

http://www.oreilly.com/catalog/perlcdbs4/
It's version 3 I have. I didn't even know there was version 4, damn!!!!

http://www.oreilly.com/catalog/perlcdbs3/ I what I have, which I actually think is better now I have had a look at it as it has perl & XML and LWP & perl = 7 books, whereas V4.0 has 6. I was going to buy mastering regluar expressions anyway, so I think I haven't lost out.


PM me or I'll give a link in the staff forum.

hey man just wondering about a few things in your backup script

i dont suppose you could explaine to me what a few things in your backup script is doing ?


like $rdiff = /usr/bin/rdiff-backup

whats this actually doing because isint $localdir = /your/localdir where u set the source for the backup ?

and remote dir where it backups to ? .

the other commands i do not understand are.

$sep and $options and $userhost (you@yourhost) is thi my hostname ?

if you could explaine this to me i would extremly greatful

$rdiff sets where the rdiff binary is located, in case you installed it somewhere else.

$sep is what goes before the print statement for print on the console.
lots of ------------------------

$options are the option for the rdiff command

$userhost is how you would log into where the backups are being saved to via SSH.

HTH.
