Have you ever ever wanted to check the contents of an area 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 approach to examine these information.
What if I informed you there was a method 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 should 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 must be put in in your Linux and macOS machines by default. Let me present you the way it’s accomplished.
Let’s say you’ve got a file named take a look at on each native and distant machines, and also you need to examine 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 handle of the distant machine and /path/to/file is the specific 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 helpful command, you possibly can examine 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.
