The checksum value of a downloaded file can be derived by the following procedure.
(1) Download the file to your machine (hereafter, this machine will be denoted as 'Your Machine')
(2) Execute the digest command to check the checksum of the file.
Ex) When the downloaded file is BBXCP2322.tar.gz
Your Machine% /usr/bin/digest -a md5 BBXCP2322.tar.gz
69073d10582a5f712d31cd6019ce675f
Compare the result of the digest command with the value (MD5) of the file described in the checksum file.
If it is the same value, the download is successful.
If it is a different value please download again as it has not been downloaded normally.
