Have you ever needed to compare the contents of a local and remote file without having to copy the remote file to the local machine and then run the diff command on both? Sure, it's not exactly a challenging task, but it's not exactly the most efficient way to compare those files.

Let's say you have a file named test on both local and remote machines, and you want to compare the contents.

Where user is a valid username on the remote machine, host is the IP address of the remote machine and /path/to/file is the explicit path to the file to be compared.

After authenticating your remote account, diff will do its thing and print out the differences between the two files.

With this handy command, you can compare different files between local and remote machines without having to first copy the files to or from one machine to another.
