This requires Win32::API, and Win32::Clipboard.
Only works on Win32 Platforms. Only really tested on Win2000, and WinXP.

Not meant to be an be all, end all, but it's a start.

Have fun!

The docs for Compress::Zlib for perl are very complex. But, the most simple use of the Module is not too bad. I've waded through the perdoc so you don't have to.

Gunzip.pl is here. I will let you know when I have Gzip.pl done.

You can do something more interesting with "success" variable.

Is this file the same as that file? The files may or may not be binary. We could compare the modify dates, or the sizes. But, those are not very accurate to know if a file has really changed.

Introducing MD5 Checksum. We can feed the files into Digest::MD5 in binary mode.

This is a great way to do Incremental Backups.

This is also an easy way to verify checksums when downloading files from the internet which list their MD5 Checksums.

You'll need the Digest::MD5 Perl Module.

Need to GZip a file using Perl?

Use Compress::Zlib.

This is a simple perl script which creates a GZip file.

This is a simple function to check if an email is valid or not.

This is a faily simple function to validate a URL being passed into your scripts. It will allow for http, https, and ftp. The beginning www. of a URL is optional as well. It will also validate if you have an IP address in place of the domain name. I'm sure this can be improved upon as this is my first attempt at regular expressions but it has worked good for me so far. Please comment or improve if your able.

Thanks!

This is as close to a perfect URL regular expression as I've come. It's based on RFC 3986.

A few caveats:

It only accepts http/https/ftp URLs by design, but you could change that to accept any valid URI pretty easily.

It doesn't support IP-based URLs or authenticated URLs. This is also by design, but you could change that with a little work.

I've found it kind of complicated to strip newline chars from a file with just the commandline. This tiny piece of code does just that.

I've found it especially useful when extracting tabulated data from a grabbed site where each cell is on a different html line. This way I can pre-filter the html, remove the newlines, and insert them again at register boundaries (row end in this case), so that with just a couple more replacement from within a regex enabled text editor I can copy&paste it directly to a database.

Another solution recommends using a text match pattern.
This works, but as long as you've got mail.jar in your classpath anyway, you might as well use this technique instead. (Plus, I think it works with older JDK 1.2+, whereas pattern.compile is 1.4+)

Note that it also accepts a comma-separated list of emails, just like a To: or CC: address line would.

I needed to send an email through an authenticated SMTP server. I found the snippet on the PHP website to do the trick.
