Here is a solution that I use: There is /usr/libexec/java_home(1) that returns the latest and greatest JDK installed on the system. See man page link below for more info. I typically do this (can be done in a login rc file; here is a bash example) : $ export JAVA_HOME=`/usr/libexec/java_home`/bin $ export PATH=$PATH:$JAVA_HOME $ which jdeps /Library/Java/JavaVirtualMachines/jdk1.9.0.jdk/Contents/Home/bin/jdeps If you don’t want to set JAVA_HOME variable , then you can use /usr/libexec/java_home —exec <cmd_name> to execute any j* command directly. eg: $ /usr/libexec/java_home —exec jdeps More information about java_home here: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/java_home.1.html two cents, - Pranav > >> >> /usr/bin/j* are linked to >> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands >> probably part of OS install and I guess it's a snapshot of JDK 7 >> commands. > > It does make sense that anything not here could be missed.
