Question

We are seeing an older version of a class being used, although we had the latest one deploy. To scan all JAR files in all subfolders of an application server, how do we write a small shell script that prints out the file name of JARS files in which this specific class is found?

Answer 1

Something like:

find . -name '*.jar' | while read jarfile; do if jar tf '$jarfile' | grep org/jboss/Main; then echo '$jarfile'; fi; done 

You can wrap that up like this:

jarscan() {   pattern=$(echo $1 | tr . /)   find . -name '*.jar' | while read jarfile; do if jar tf '$jarfile' | grep '$pattern'; then echo '$jarfile'; fi; done } 

And then jarscan org.jboss.Main will search for that class in all jar files found under the current directory
