As most people here know, when using bash at the command prompt if you partially type a file name a command or an option to a command etc, bash will complete the word if there is exactly one match.
When there is more than one match, you need to hit
<Tab> twice and bash will generate a list of possible matches.
I would like to configure bash to simply provide those options on the first
Is this possible without writing a script? i.e. a shell option?
man bash has a section "programmable completion" but I couldn't make out if there is an option to enable "single tab completion".
