Check md5sum of ISO on Linux

After downloading a Linux ISO file it is wise to check it's md5 value. The result will show you that the file is not corrupted and it is safe to use. The MD5 calculation gives a checksum result should be equal with the supplied number. It confirm both file integrity and authenticity. I am writing a simple method to check MD5 (Message Digest algorithm 5) using Ubuntu. This method is same in most linux operating system.

First of all Open terminal.
Go to the folder where your downloaded ISO file is located. Use 'cd FOLDER-NAME' command to explore folders/ directories. Replace 'FOLDER-NAME' with correct syntax. Remember that linux is case sensitive.

Now type

md5sum FILE-NAME
(It may look like =  md5sum xubuntu-12.04-desktop-i386.iso )
Then after some seconds a result will show like the line below
52fddd81e75bb421a5435a42ca9ec6df xubuntu-12.04-desktop-i386.iso

Now check that number from corresponding website or supplied text file that if both number is same or not. If both number is matched then your ISO file is OK to burn on a DVD. It is safe to install and explore.

You can apply this method on Ubuntu (all varients), LinuxMint, Peppermint, Edubuntu, Lubuntu, Xubuntu, Kubuntu, antiX, Puppylinux or anyother Linux operating system.
