我在logrotate 3.12.2中的prerotate脚本有问题。 我在prerotate/endscript部分中指定的脚本没有接收到要作为第一个参数（ $1 ）旋转的文件的名称。
这是logrotateconfiguration：
compress /external-logs/syslog { daily rotate 3 olddir OLD missingok prerotate /root/filter-syslog.sh endscript }
这里是/root/filter-syslog.sh ：
#!/bin/sh echo "log file subject to prerotate: $1"
最后，这里是logrotate run的详细输出：

在上面的输出中注意“ log file subject to prerotate: ”的行。 为什么不是行输出“ log file subject to prerotate: /external-logs/syslog ”而不是？
你没有把任何东西传递给你的shell脚本。 所以在你的/root/filter-syslog.sh $1没有值，因此没有打印任何东西。
回声“日志文件需要prerotate：$ 1”
为了使其工作，您必须在您的logrotateconfiguration中传递$1或$@ 。
compress /external-logs/syslog { daily rotate 9 olddir OLD missingok prerotate /root/filter-syslog.sh $1 endscript }
