Md5sum filename1 filename2 filename3 Generate MD5 Checksum and ouptut to file The filename and checksum compare all the files in the directory with the corresponding filename and calculate each file’s checksum. Md5sum filename Generate MD5 Checksum on multiple files The command with the ‘-c’ flag is run to compare the checksum with the value in the SHA256SUMS file. If the two checksums match, that means the files are identical – no corruption has occurred. In order to verify if it has been corrupted or not, the publisher of the file you downloaded can include a MD5 Checksum (a string of numbers of letters) which is compared to the file you just downloaded. Most vendors offer a checksum (or a checksum-like code) corresponding to the file (s) being downloaded. For example, it is possible for file to be corrupted in the process of downloading it from a website or FTP server. In Linux, there’s a command line tool that you can use to create/verify checksum. For those of you that are not familiar with MD5 Checksums, the purpose is to validate the integrity of a file that may have been corrupted or tampered with.
