xzcmp

The xzcmp command line tool is a part of the XZ Utilities package. It is used to compare the compressed files in the xz format. The xz format is a high-compression data compression format that typically replaces the gzip format. The tool takes two input files and compares them to check whether their compressed data is identical or not. If the compressed data of the input files is the same, it displays a message indicating that they are identical. In case the compressed data is different, it reports the byte positions where the comparison found a mismatch. The xzcmp tool is particularly useful when working with large compressed files and you want to compare their contents quickly. It is also sometimes used to verify the integrity of compressed archives. Along with xzcmp, other tools in the XZ Utilities package include xzcat, xzdiff, xzgrep, xzless, xzmore, and xzegrep, each specializing in a specific operation related to the xz format.
