Diff command to compare files on different servers--Unix [closed]

Question

Can I use the diff command to compare files on two different servers? If not, is there any other option?

Answer 1

You can copy the file over from the other server using scp and then use diff.

Or ssh to the remote host and diff using a single command like this:

ssh user@remote "cat /path/to/remote/file" | diff - /path/to/local/file
