在启动时附加到屏幕会话

我想要做的是通过 crontab 在启动时启动屏幕会话，然后让用户自动连接到该会话。

这是我当前的 cron 文件：

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command

@reboot screen -dmS RunScript sh /root/start.sh

这里创建了屏幕会话，但是如果不手动运行连接到会话命令，我似乎无法连接到它。

我可以跑

screen -dmS RunScript sh /root/start.sh && screen -r RunScript

为了启动会话并连接到它，但是，它不适用于 crontab，因为我认为它是一个单独的过程。

有什么方法可以实现这个吗？谢谢！

我设法通过让服务在启动时运行启动脚本，然后通过 .bash_login 文件连接到屏幕会话来完成我想做的事情
