Try
尝试
su minecraft -c '/bin/bash /path/to/script/script.sh &'
- The user should be the first argument to su.
- You should use quotes and not ticks for the command argument (-c)
- You may want to consider using
su -l minecraftto have the script run in an environment which would be similar to that if the user minecraft logged in directly.
- 用户应该是 su 的第一个参数。
- 对于命令参数 (-c)，您应该使用引号而不是刻度
- 您可能需要考虑使用
su -l minecraft让脚本在类似于用户 minecraft 直接登录的环境中运行。
Give this a shot and let me know if it works.
试一试，让我知道它是否有效。
