Perl script to unzip a single file from a Zip.

# file: UnzipOneFile.pl

use chilkat;

# Unzip a single file contained within a Zip archive.
$zip = new chilkat::CkZip();
$zip->UnlockComponent("anything for 30-day trial");

# Open an already-existing zip
$success = $zip->OpenZip("exampleData.zip");
if ($success)
{
	# Locate the file to be unzipped.
	# The zip in this example contains these files and directories:
	# exampleData\
	# exampleData\hamlet.xml
	# exampleData\123\
	# exampleData\aaa\
	# exampleData\123\hello.txt
	# exampleData\aaa\banner.gif
	# exampleData\aaa\dude.gif
	# exampleData\aaa\xyz\	
	
	# When passing directory paths, either forward and backward slashes can be used.
	$zipEntry = $zip->FirstMatchingEntry("*aaa/dude.gif");
	if ($zipEntry != null) 
	{
		# Extract dude.gif into the images subdirectory regardless of the
		# path included with the entry within the $zip->
		$zipEntry->ExtractInto("images");
		
		# If we called "Extract" like this:
		$zipEntry->Extract("images");
		# the component would create dude.gif in "images/exampleData/aaa"
	}
	else
	{
		# Failed to find the file.
		$zip->SaveLastError("findMatchingEntryLog.txt");
	}	
}	
else
{
	# Failed to open the .zip archive.
	$zip->SaveLastError("openZipError.txt");
