如何根据当前操作系统运行Tmux命令？

我想在 Linux 和 macOS 上使用相同的 Tmux 配置文件，但某些配置（例如将 Tmux 与系统剪贴板集成）无法跨平台移植。

我已阅读有关该if-shell命令的信息，但一些资源说这是一个异步操作（在后台执行），因此会话可能无法正确配置（为什么？）。

~/.tmux.conf:

# vim copy to system clipboard
bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "pbcopy"
#bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "xclip -in -selection clipboard"

根据当前操作系统（Linux 或 macOS），在 Tmux 中执行条件命令：

# vim copy to system clipboard
if-shell '[[ $(uname -s) = Linux ]]' { 
   bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "xclip -in -selection clipboard" 
} { 
   bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "pbcopy" 
}

if-shell支持选项（ ）在后台-b运行；shell-command默认情况下，它立即运行：

if-shell [-bF] [-t target-pane] shell-command command [command]
              (alias: if)
        Execute the first command if shell-command returns success or the second command otherwise.  Before being executed, shell-command is expanded using the rules specified in the FORMATS section,
        including those relevant to target-pane.  With -b, shell-command is run in the background.

还 （man tmux）：

Commands like if-shell, run-shell and display-panes stop execution of subsequent commands on the queue until something happens - if-shell and run-shell until a shell command finishes and display-panes until a key is pressed.  For example, the following commands:

           new-session; new-window
           if-shell "true" "split-window"
           kill-session

Will execute new-session, new-window, if-shell, the shell command true(1), split-window and kill-session in that order.
