I've downloaded Java (jdk-6u31-linux-x64.bin) from I run the executable, files are successfully unpacked, but then there is a message about registration and it sits at

Press Enter to continue...

I need to be able to run this automatically from a script. Is there a straightforward way to skip or automatically dismiss this prompt?

If your Linux is Debian, you should use java-package to turn that .bin into a .deb. Which shouldn't display that message. – Dan D. May 1 '12 at 23:56

touch answers && ./jdk-6u31-linux-x64.bin < answers && rm answers

This command does the following:

  1. touch answers Create an empty text file called answers in the current directory
  2. ./jdk-6u31-linux-x64.bin < answers Execute the Java installer and redirect stdin from the empty answers file
  3. rm answers Delete the temporary file when finished
  4. && Combine three operation into a single line. Only execute the next command if the previous command completed successfully

When suggesting a user execute commands, it's helpful to explain what they do. – Darth Android May 2 '12 at 3:26
I think you want && instead of & – bstpierre May 2 '12 at 14:19
& will run them simultaneously, && will run as long as the previous exited successfully (exit code 0), and ; will run after the previous command is finished regardless of it's exit code. – Rob May 2 '12 at 14:40
You're correct. Update to use &&. – Mike Willekes May 2 '12 at 17:02
