I am searching for a .class file inside a bunch of jars.

jar tf abc.jar 

works for one file. I tried

find -name \"*.jar\" | xa         


        

Answer 1

I faced a similar situation where I need to search for a class in a list of jar files present in a directory. Also I wanted to know from which jar file the class belongs to. I used this below code snippet(shell script) and found out to be helpful. Below script will list down the jar files that contains the class to be searched.

#!/bin/sh
LOOK_FOR="codehaus/xfire/spring"
for i in `find . -name "*jar"`
do
  echo "Looking in $i ..."
  jar tvf $i | grep $LOOK_FOR > /dev/null
  if [ $? == 0 ]
  then
    echo "==> Found \"$LOOK_FOR\" in $i"
  fi
done
