Find a text pattern in jar files

Tagged jar, find, search, recursive, linux, unzip  Languages bash

Helpful when you need to find a class or package in some jar file recursively below the current directory. Still needs a test to see if the file found was a file or directory. Works case insensitively. Uses the unzip command because of it's performance superiority in comparison to jar.

for f in find . -type f -name '*\.jar'
        unzip -l $f | grep -i $1 && echo "was found in $f"
