  • tmux-plugins/tmux-resurrect – Restore tmux environment after a system restart. Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects. tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux. http://undeadly.org/cgi?action=article&sid=20140904174329

  • tmux for MobaXterm | techslaves.org – An old friend meets a new friend: tmux for MobaXterm! In a previous sysadmin life, I used tmux to good effect. Today, I’m using a Windows 8.1 system as my primary work desktop and recently got into MobaXterm for my Linux/terminal/X11 needs. While my most common usage scenario for tmux is invoking it on a remote server/VM instead of directly on my local machine, I thought it would be a good exercise to install tmux for local usage on MobaXterm and sharing that work by creating a plugin.

The script does not use any 3rd-party perl modules, unless the –save/days/max command-line options are used, in which case you will need to have the DBD::SQLite module installed. It should work on any UNIX server that provides /proc/meminfo, /proc/*/exe, /proc/*/stat, and /proc/*/statm files. You will probably have to run the script as root for it to read the /proc/*/exe symbolic links.
