我很好奇是否有人在从cron运行脚本时遇到类似的问题。这行脚本应该将opentsdb_daemon.log文件复制到opentsdb_daemon_with_pid.log。目前，openTSDB仅在一个PID上运行。
!/bin/sh
cp -f /opt/opentsdb/opentsdb-2.2.0/var/log/opentsdb/opentsdb_daemon.log "/opt/opentsdb/opentsdb-2.2.0/var/log/opentsdb/opentsdb_daemon_pid_$(ps -ef | grep [o]pentsdb | awk '{print $2}').log
运行正常。文件opentsdb_daemon_pid_76079.log已创建，但在运行fron cron时，它会创建如下内容：opentsdb_daemon_pid_63453?63454?76079.log
我试图从不同的cron用户运行它 - 具有相同的效果。我会非常感谢任何建议。

应该在cron运行时返回多个PID，你得到的是由“？”分隔的所有PID
“？”是因为ps -ef | grep [o]pentsdb | awk '{print $2}'未正确显示在文件名
我认为这是因为当cron执行命令时，命令出现在进程列表中，所以：
\n也是grep [o]pentsdb;）
您可以通过两个连续的PID 63453和63454确定它，它们是“cron执行命令xxx”的进程行，而这个进程的子进程是“命令xxx”
也许解决方案可能是添加类似：
grep [o]pentsdb
