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.

This is a little example of how to use threads in Perl. It creates three threads and runs them... That's it...

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.

Get a FileSize

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!

Need to GZip a file using Perl?

Use Compress::Zlib.

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

Function to capitalize the first letter in every word in a string, but only if the entire string is in ALL CAPS.

Example:
"I LIKE TO SCREAM" becomes "I Like To Scream"
"I LIKE to RUN" remains "I LIKE to RUN".

A database API written in Perl for a MySQL.

You will need to edit the settings for your server.

Prints the user's IP address and localtime on a web page.

Simple function to check for a valid email address. Makes sure the @ and a . are in the right place. There is most likely a perl package on CPAN that would be more extensive, but this happens to work for my uses.
