Seriously, I think there’s hardly any more productive and more versatile tool for a software developer than the terminal. Maybe it’s the hacker/wizard/neckbeard kind of feeling I get when using a terminal, I don’t know. At work we do lots of pair programming. Everyone’s got their own laptop and can set it up the way they like. And since I love working with the command line I’ve spent quite some time doing (only sane! I swear!) modications to my terminal environment that make working with the command line more pleasant and streamlined. This is why my pair usually will be greeted by something like this: https://www.hamvocke.com/blog/a-quick-and-easy-guide-to-tmux/ 1/21 7/24/2018 A Quick and Easy Guide to tmux If they’ve worked with me before they know what they are up to. But every once in a while there will be a new team member who doesn’t know my environment. Usually this is the point where they will ask something like “WTF am I looking at?” and it’s my time to shine! Because what they’re looking at is nothing less than the best thing since sliced bread.

  • Tmux: Terminal Multiplexer
    tmux: Terminal Multiplexer Tom Ryder [email protected] https://sanctum.geek.nz/ What is tmux? ● tmux is a terminal multiplexer. ● Runs in the TTY, or your favourite terminal emulator ● Start any number of virtual terminals within it ● Arrange terminals in any way you like ● And most importantly: Attach/detach without interrupting running programs ● Extremely useful for sysadmin work where X is unavailable, and many other things Simple use case ● You SSH in to your faraway server. ● You start a process interactively, that you think will only take a few minutes... – ...but it takes ages! – ...and you forgot to redirect the output to a file! – ...and interrupting the process will break things! – ...and your laptop is running out of battery! ● What to do? Simple use case ● The shell way: Bash: $ long-running-job [Ctrl-Z] to suspend $ bg $ disown $ logout Still works, and useful to remember in a pinch! ● Lets the process complete safely, but... ● ...you lose all the output, and you can’t (easily) “adopt” the process again. ● Your job has a dependency on your SSH connection. ● If only we could fix that... Simple use case ● The multiplexer way: tmux: $ tmux $ long-running-job [Ctrl-B, d] to detach $ logout ● And then later: $ ssh yourhost $ tmux attach ● And your job’s output is sitting there, like you never left. Another use case ● You run a program like Mutt on a server to read and write mail ● Your connection is flaky ● Every time your SSH connection cuts, you completely lose the message you were writing, or your place in the mail queue

  • Mosh Research Paper
    Mosh: An Interactive Remote Shell for Mobile Clients Keith Winstein and Hari Balakrishnan M.I.T. Computer Science and Artificial Intelligence Laboratory, Cambridge, Mass. fkeithw,[email protected] Abstract Figure 1: Mosh in use. Mosh (mobile shell) is a remote terminal application that supports intermittent connectivity, allows roaming, and speculatively and safely echoes user keystrokes for better interactive response over high-latency paths. Mosh is built on the State Synchronization Protocol (SSP), a new UDP-based protocol that securely synchronizes client and server state, even across changes of the client’s IP address. Mosh uses SSP to synchronize a character- cell terminal emulator, maintaining terminal state at both client and server to predictively echo keystrokes. Our evaluation analyzed keystroke traces from six different users covering a period of 40 hours of real-world us- age. Mosh was able to immediately display the ef- fects of 70% of the user keystrokes. Over a commer- cial EV-DO (3G) network, median keystroke response mote servers feel more like the local computer, because latency with Mosh was less than 5 ms, compared with most keystrokes are reflected immediately on the user’s 503 ms for SSH. Mosh is free software, available from display—even in full-screen programs like a text editor http://mosh.mit.edu. It was downloaded more than or mail reader. 15,000 times in the first week of its release. These features are possible because Mosh operates at a different layer from SSH. While SSH securely con- 1 Introduction veys an octet-stream over the network and then hands it off to a separate client-side terminal emulator to be inter- Remote terminal applications are almost as old as packet- preted and rendered in cells on the screen, Mosh contains switched data networks.
