Instructions on using md5 checksums
To check a checksum agianst a file:
Ussually, and md5 checksum file containes the name of the file it was created for, so you simply need to run md5sum, with the -c parameter, followed by the filename of the checksum file.
md5sum -c downloadedfile.tar.gz.md5.
The checksumfile is often placed in the same directory as the file it was created for.
To create a checksum file:
md5sum file.tar.gz > file.tar.gz.md5
The first file name if the name of the file that we want to create the checksum for, and the second is the file in which the checksum will be stored.
