How to clear Catalina Out without disabling further logging?

Our Catalina The out file becomes very large every once in a while (yes, I implemented slf4j and logback in my application to prevent this in the future) But now, when I go to the circular log, I will Catalina Out copy to Catalina {date} and execute cat / dev / null > Catalina Out The problem is that after I do this, Tomcat will no longer capture logs until Tomcat restarts the next morning, which is not ideal Why is that? Is there any way to avoid it?

Solution

As easy as a cake: echo > Catalina Out The file descriptor will not change, and Java can continue to write to the file
