The resurrect-hook-post-save-all hook is somewhat fragile as it relies on the user's PATH for commands like grep, readlink, and mv. In a Nix environment, it's more robust to use absolute paths from pkgs. Additionally, using $HOME instead of ~ and adding a check for the existence of the last symlink improves reliability.

          set -g @resurrect-hook-post-save-all 'd=$HOME/.tmux/resurrect; [ -L "$d/last" ] && f="$d/$(${pkgs.coreutils}/bin/readlink "$d/last")" && ${pkgs.gnugrep}/bin/grep -P "^(pane|window)\twork\t" "$f" > "$f.tmp" && ${pkgs.coreutils}/bin/printf "state\twork\n" >> "$f.tmp" && ${pkgs.coreutils}/bin/mv "$f.tmp" "$f"'
