当套接字在那里时如何重新连接到屏幕会话，但屏幕不会使用它？

Question

我见过这个问题和这个问题，但它们都不适用于我。我在 /var/run/screen 中有套接字文件并且我拥有它 - 但 screen -list 无法识别它并允许我连接。我怎样才能恢复这个会话？

tom@host~ $ ls /var/run/screen/S-tom/

tom@host ~ $ screen -list
No Sockets found in /home/tom/.screen.

您可以将SCREENDIR环境变量设置为/var/run/screen. 然后，您应该能够列出和连接。

假设sh兼容的外壳：

export SCREENDIR="/var/run/screen"

从 man 1 screen
