我有一个场景，我需要通过 grepping 实例名称并将其所有相关异常写入 Instance.txt 从日志文件中准备/写入文件的异常
示例 test-dom-01.txt,test-dom-01.txt,test-dom-04.txt ...等等及其相关错误
输出日志

问是我必须将现有的异常移到每个文件中，而忽略其余的行，只是异常必须移到单独的文件中
test-dom-01文件的预期输出为test- dom-01.tx t，内容为
catalina.0.log:INFO: Error parsing HTTP request header
catalina.0.log:java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens
catalina.0.log:java.lang.IllegalArgumentException: Invalid character found in the HTTP protocol
catalina.0.log:java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in
catalina.0.log:SEVERE: Exception when trying to read white list from probably because file list is empty
tests-rs-dom2-1 的预期输出是 tests-rs-dom2-1.txt
catalina.0.log:INFO: Error parsing HTTP request header
catalina.0.log:java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

试过：
awk '/on instance: test-dom-01/,/ /' out.log > test-dom-01.txt
但没有运气
