如何找出我的 tmux 会话的 PID？

找到了困难的方法不同套接字下的启动tmux会话未列出tmux ls，因为它只是tmux -L default list-sessions显示属于default套接字的会话的快捷方式。 （我在用tmux -L 继承tmux调用 shell 的环境.)

tmux ls不显示会话的 PID：

$ tmux -L default ls
1: 1 windows (created Thu Mar 30 09:39:31 2023) (attached)

$ tmux -L lofa ls
0: 1 windows (created Tue Apr 25 15:12:00 2023) (attached)
2: 1 windows (created Tue Apr 25 16:25:38 2023)

我天真地尝试通过开始时间来匹配该过程，尽管我可以推断出哪个会话是哪个会话，因为lofas 会话的开始时间确实匹配并且只剩下一个是defaults ，但default会话的时间明显不同。

$ ps x -o lstart,pid,stat,args f

tmux list-sessions接受格式字符串（请参阅“格式”部分在手册页中）：

$ tmux ls  -F 'socket_path: #{socket_path} | session_name: #{session_name} | server_pid: #{pid} | pane_pid: #{pane_pid}'
socket_path: /tmp/tmux-1000/default | session_name: 1 | server_pid: 32710 | pane_pid: 1187196

$ tmux -L lofa ls  -F 'socket_path: #{socket_path} | session_name: #{session_name} | server_pid: #{pid} | pane_pid: #{pane_pid}'
socket_path: /tmp/tmux-1000/lofa | session_name: 0 | server_pid: 2391032 | pane_pid: 2391033
socket_path: /tmp/tmux-1000/lofa | session_name: 2 | server_pid: 2391032 | pane_pid: 2393553

或者使用换行符：

$ tmux -L lofa ls -F \
> 'socket_path: #{socket_path}
> └── session_name: #{session_name} | server_pid: #{pid} | pane_pid: #{pane_pid}'

socket_path: /tmp/tmux-1000/lofa
└── session_name: 0 | server_pid: 2391032 | pane_pid: 2391033
socket_path: /tmp/tmux-1000/lofa
└── session_name: 2 | server_pid: 2391032 | pane_pid: 2393553
