It is a step-by-step information on the best way to evaluate the contents of native and distant information with the assistance of SSH. Watch the companion video tutorial by Jack Wallen.

Have you ever ever wanted to check the contents of a neighborhood and distant file with out having to repeat the distant file to the native machine after which run the diff command on each? Certain, it’s not precisely a difficult process, but it surely’s not precisely essentially the most environment friendly strategy to evaluate these information.

What if I informed you there was a means to do that with out having to first copy that file from one machine to a different? This ensures you don’t all the time need to first copy a contemporary model of the file to get essentially the most up-to-date content material. We do that with the assistance of the three instructions SSH, cat and diff, all of which needs to be put in in your Linux and macOS machines by default. Let me present you the way it’s carried out.

Let’s say you’ve a file named take a look at on each native and distant machines, and also you need to evaluate the contents. To do that, open a terminal on one machine and enter the command

ssh person@host cat /path/to/file | diff /path/to/file -.

the place person is a legitimate username on the distant machine, host is the IP tackle of the distant machine and /path/to/file is the express path to the file to be in contrast. After authenticating your distant account, diff will do its factor and print out the variations between the 2 information. And that’s all there may be to it.

With this useful command, you’ll be able to evaluate completely different information between native and distant machines with out having to first copy the information to or from one machine to a different. As all the time, it’s higher to work smarter, not more durable.
