Possibly. I find sh more usable than stock csh, though shells are almost as personal an issue as keyboards or editors. If you think of telnet, the program, as strictly an interface to telnet, the remote login protocol, then I can see how you might think it reasonable to drop it. But telnet-the-program hasn't been just that for...decades, at the very least. Every telnet I can recall, clear back to the days (circa 4.2BSD) when my wetware memory isn't reliable any longer, accepted a port number and was extremely useful for dealing with any of various possible networking issues. To name three real uses I've made of it recently: to check what a remote sshd banners as, to check what an RFB server banners as, and (in conjunction with script(1) to capture the output of a one-off server set up to transfer a text file (this being the use case I had for it on the Pi 3). netstat, that's a completely different issue. There's no "clear text protocol" issue there. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
