The command worked. It found several java executables: /usr/java/jdk64-1.8.0_151/bin/java /usr/java/jdk64-1.8.0_151/jre/bin/java /usr/java/jre64-1.8.0_111/bin/java /usr/java/jre64-1.8.0_111/jre/bin/java
If you look closely at the output you got from your command, you will see that there is a list of strings called "stdout_lines" that contains the paths to the java executables that the command located. You can extract them as simply as result.stdout_lines[0] or whatever. There were some directories that the find command could not recurse through, so it reported "permission denied" on those directories. I'm sorry - I can't offer a complete solution, only ideas. The most important idea though, is that you almost certainly should not be searching for an executable you intend to run. You should know where it is. If your use case requires you to search for java, maybe you can compromise: Set up a list of likely locations, look for it in each of those locations in turn, and if it is not found in one of those locations, abort. If you really want to persist with searching for it, you could use filters to split up the lines in the stdout result, select only those lines that match ".*java$" - those paths will be paths to executables. You could for example run this command: find -L /usr -executable -type f -name "java" -print 2>/dev/null | grep "/java$" That command will discard any errors, and return ONLY lines that refer to an executable called "java". The command will return zero if there are any java executables and will fail with non-zzero code only of there are no java executables found. Regards, K.
