FSUM is a fast and handy command line utility for file integrity verification. It offers a choice of 13 of the most popular hash and checksum functions for file message digest and checksum calculation.

You can easily use FSUM with a batch wrapper to do automated file integrity monitoring, and use something like blat to email you any differences.

The most common use for FSUM is checking data files for corruption. A message digest or checksum calculation might be performed on data before transferring it from one location to another. Making the same calculation after the transfer and comparing the before and after results, you can determine if the received data is corrupted or not. If the results match, then the received data is likely accurate.
