Making "java -v", "java --version", and "java version" Work

To get the version of most CLI tools, you type the tool’s command name followed by one of these:

• -v
• –version

Some CLI tools, like Git, support a “version” subcommand, so you type the tool’s command name followed by “version”.

Java supports none of these.

Instead, you must type:

java -version\

I’m too old to remember that, so I’ve created a bash/zsh function:

Now I can type any of the following:

java -v
java –version
java version
java -version\

And they all give me Java version information.
