Hi rbatte1 and Rudi,


Thanks for the reply.

My intention is when ever I run the below command, if the output is successful then I want to print successful output need to ignore if the command output is not successfull.
Code:
$i -classpath $loc4 org.apache.catalina.util.ServerInfo

But I tried to redirect the output but still getting error messages.
Code:
Error: Could not find or load main class org.apache.catalina.util.ServerInfo
{"'tomcat'":"'Server version: Apache Tomcat/9.0.30 Server built: Dec 7 2019 16:42:04 UTC Server number: 9.0.30.0 OS Name: Linux OS Version: 3.10.0-1062.9.1.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_171-b11 JVM Vendor: Oracle Corporation'"}

Please wrap all code, files, input & output/errors in CODE tags.
It makes them easier to read and preserves spacing for indenting or fixed-width data.
