(Ruby) Check if a File is in Gzip Format

See more Gzip Examples

This example demonstrates how to use the ExamineFile method to determine whether a file is in Gzip format.

The method inspects the contents of the specified file and returns true if the file is recognized as a valid Gzip file, or false if it is not. This is useful for validating input files before attempting to decompress them.

If the method fails (for example, if the file does not exist or cannot be accessed), the CHECK_SUCCESS macro reports the error.

# The file to examine:

# Check if the file is a valid Gzip file:

if (isGzip == true)
    print "The file is a valid Gzip file." + "\n";
else
    print "The file isnot a Gzip file." + "\n";
