What's the difference between SFTP, SCP and FISH protocols?
I use SSH for remote file systems access. And I use Krusader file manager. Krusader offers a choice of FTP, SMB, FISH and SFTP connection protocols, and both FISH and SFTP work with an SSH server. What's the difference among FISH and SFTP?
PS: I don't specify Krusader in the question title because Midnight Commander, for example, supports FISH as well, so that FISH can be something not limited to Krusader.
