compiled by Sven Guckes  screen-vs-tmux(at)guckes.net

screen vs tmux:

license:
screen: since 1987: GPL.
tmux:   since 2007: BSD.

both: session names, remote control

* copy: from/to, linewise, blocks
screen--:
* starts without showing any windows or help. :-(
* copy mode: exists mode when using a non-bound key
    -> repeat selection all over again :-(
* splits: there is only *one* (global) layout. :-(
* reattach: loses the current window layout (all hor/ver splits). :-(
* language: doesnt have an internal language.
    so you cannot create variables and you cannot
    make decisions (branches) on anything.
    so it's hard to automize and script. :-(
screen++:
* zombie mode: see date+time of detach of process
       together with exit status and error messages;
       with ":zombie z" you kill it off with 'z', otherwise
       resurrect process the with CTRL-SPACE (fixed key binding)
* multiuser mode: you can add/remove other users
    to view your session through ACL commands, eg:
    acladd user1,user2,user3
    acldel user23,user42
    as well as change their permissions
    aclchg user5,user23,user42 -w+x #
    these users may NOT write to the window (-2)
    -w  no write. cannot write into windows.
    +x  execute.  command execution possible.
    #   "for all windows"
* copy mode: can join lines of selection in four different ways:
    "direct", with blanks, with commata, with LF.
* read directly from a device (eg /dev/ttya)
tmux++:
* better source code
* much bigger community
* book: by Brian P. Hogan:
    "tmux- Pragmatic mouse-free development"
    ISBN-13: 978-1-934356-96-8

* book: by Nate Dickson:
    "Painless Tmux - A Sane Person's Guide to Command Line Happiness"
    https://leanpub.com/painless_tmux/
* scripting language -> easier solutions
* many plugins
* every window has its own page layout
* can search for string in *all* open windows.
* plugin copycat: search for *pattern* in all windows
* window numbering starts at "1" (screen: always at "0")
* has multiple paste buffers (screen has only one)
* command line: has tab completion for command names

TODO:
* dependencies on libraries
* copy mode key bindings: screen:vi, tmux:emacs
* limitations: screen: windows numbers 0-99
