cksum – compare for multiple files.
If you have to compare cksum for couple of files, the you know how cumbersome it is. So, I wrote a simple script, wherein you can create a file called cksums in the current directory and copy paste the result of “**cksums ***” into this file, and then run this script. Cool 🙂
