Start tomcat and output logs at the same time

When tomcat is started and logs are output at the same time, execute startup. sh script to start tomcat. the execution result is as follows: To view the log, you have to cd it to the logs directory, and then run the tai-f command to view the log. several more steps are required.

If you can output logs while executing the script, can it slightly improve the efficiency. How to set it? This is a method of laziness, which has been tested and verified in catalina. sh elif ["$1" = "start"]; if ["$1" = "-security"] in then; else eval \ "$ _ RUNJAVA \" \ "$ LOGGING_CONFIG \" $ JAVA_OPTS $ CATALINA_OPTS \-Djava in then. endorsed. dirs = \ "$ JAVA_ENDORSED_DIRS \"-classpath \ "$ CLASSPATH \" \-Dcatalina. base = \ "$ CATALINA_BASE \" \-Dcatalina. home = \ "$ CATALINA_HOME \" \-Djava. io. tmpdir = \ "$ CATALINA_TMPDIR \" \ org. apache. catalina. startup. bootstrap "$ @ "Start \>" $ CATALINA_OUT "2> & 1" & "is added with a line feed: tail-f $ {CATALINA_OUT} [plain] else eval \ "$ _ RUNJAVA \" \ "$ LOGGING_CONFIG \" $ JAVA_OPTS $ CATALINA_OPTS \-Djava. endorsed. dirs = \ "$ JAVA_ENDORSED_DIRS \"-classpath \ "$ CLASSPATH \" \-Dcatalina. base = \ "$ CATALINA_BASE \" \-Dcatalina. home = \ "$ CATALINA_HOME \" \-Djava. io. tmpdir = \ "$ CATALINA_TMPDIR \" \ org. apache. catalina. startup. bootstrap "$ @" start \> "$ CATALINA_O UT "2> & 1" & "tail-f $ {CATALINA_OUT} fi again sh startup. sh start tomcat, log output, OK, get it done!
