Thanks for your reply but I'm a bit confused. You said that readline uses
what's found in the file system rather than preserving what the user typed.
But for my example, ~/MyDir should be found in the file system but why it's
completed as ~/myDir? Readline behaves differently between word completion
and command completion? Or, command completion is done by Bash itself other
than readline? And I noticed that if I first input /home/myname/my and than
press TAB, it'll be correctly completed as /home/myname/MyDir . What's the
difference?
