MD5 Checksum

by Michael Greifenkamp (March 16th, 2010)

This works for OS X and Linux.

When you download a large file (an CD or DVD ISO for instance) and want to check the MD5 checksum for that file, simply do the following:

openssl md5 filename.iso

It will return with the checksum of the file, which you can then compare to the value that the download site (hopefully) lists.
