About

This plugin goes to great lengths to save and restore all the details from your tmux environment. Here's what's been taken care of:

• all sessions, windows, panes and their order
• current working directory for each pane
• exact pane layouts within windows (even when zoomed)
• active and alternative session
• active and alternative window for each session
• windows with focus
• active pane for each window
• "grouped sessions" (useful feature when using tmux with multiple monitors)
• programs running within a pane! More details in the restoring programs doc.

Optional:

• restoring vim and neovim sessions
• restoring pane contents
• restoring a previously saved environment

Installing TPM (Tmux Plugin Manager) , Tmux Resurrect and Tmux Continuum

• In ~/.tmux/plugins/

git clone https://github.com/tmux-plugins/tpm.git
git clone https://github.com/tmux-plugins/tmux-resurrect.git
git clone https://github.com/tmux-plugins/tmux-continuum.git

• In a tmux window

prefix + I

• Installs new plugins from GitHub or any other git repository

• Refreshes TMUX environment

• Create a directory ~/.tmux/resurrect/

  • This is where tmux-resurrect and tmux-continuum saves are located
  • Do nothing and tmux-continuum saves automatically every 15 mins
  • At any time use Prefix + Ctrl-s to save a snapshot of your session
  • To restore a session to the last save before a reboot
    • use Prefix + Ctrl-s

Here are the steps to restore to a previous point in time:

• make sure you start this with a "fresh" tmux instance
• $ cd ~/.tmux/resurrect/
• locate the save file you'd like to use for restore (file names have a stamp)
• symlink the last file to the desired save file: $ ln -sf <file_name> last
• do a restore with tmux-resurrect key: Prefix + Ctrl-r
