With bash
, I can complete a command with TAB. Normally, it should also complete the command line switches: eg when I typed:
java -
it should show me the possibilities. It does not. How can I enable this preview?

In the answers to that question there were several links to documentation. You might find what you look for there.
You need to have bash_completion
installed and then just add . /etc/bash_completion
. /etc/bash_completion
to your .bashrc
.

Depending on what Linux flavor you're using, you may want to add a package. For Fedora and related distributions, you need to add the separate package bash-completion
to get this to work. I wouldn't be surprised if other distributions had this packaged as an optional 2nd package that you need to add in addition to the bash
package.
