How do I redirect stdin from a shell script to a command in the shell script? I am trying to pass the stdin to a java System.in stream.
I want to replace
find . -type f | $JAVA_HOME/bin/java com.domain.BatchProcess
with
find . -type f | ./batch.sh

If you exec the command within the script, it will replace the shell and inherit it's file/java com.domain.BatchProcess
is expecting input from stdin, then putting it in a script and running.
