使用 ls 命令在 proc 目录中查找进程所有者
ls -ld /proc/816
如果你有 stat 命令，你可以使用漂亮的格式显示只有所有者：
stat -c '%U' /proc/775
avahi
奖励：打印你的用户名而不查看 $USER
stat -c '%U' /proc/$$
英文:
Use ls to find the process owner in the proc directory
ls -ld /proc/816
If you have stat you can display just the owner with fancy formatting:
stat -c '%U' /proc/775
avahi
Bonus: print your user name without looking at $USER
stat -c '%U' /proc/$$

你可以在/proc/YOUR_PROCESS_ID/status中找到与进程相关的所有信息，其中YOUR_PROCESS_ID是你的进程的PID。
因此，你可以通过运行类似以下命令来获取进程的所有者：
cat /proc/YOUR_PROCESS_ID/status | grep "Uid" | cut -f 2 | id -nu
英文:
You can find all the information relative to a process in /proc/YOUR_PROCESS_ID/status where YOUR_PROCESS_IDis the PID of your process.
Therefore, you could get the owner of the process by simply running something like this:
cat /proc/YOUR_PROCESS_ID/status | grep "Uid" | cut -f 2 | id -nu
