Hi,
Bash ships with lots of useful completion functions, but if you don't
bind them to keys, then less people will use them.
- In bash's emacs keymap, please bind dynamic-complete-history to
M-/, since it's sort of like Emacs's dabbrev-expand -- it looks

You'd need single quotes instead of double there. (And == is illegal in
Bourne/POSIX shell test commands; only bash tolerates it.) You could

In the shell, a variable is not set until it has been assigned a value.
An array variable is not set unless one of its indices has been assigned
a value.
