For bash, this is enough:
# Bash TAB-completition enhancements
# Case-insensitive
bind "set completion-ignore-case on"
# Treat - and _ as equivalent in tab-compl
bind "set completion-map-case on"
# Expand options on the _first_ TAB press.
bind "set show-all-if-ambiguous on"
If you also add e.g.CDPATH=~/Documents, it will also always autocomplete from your Documents no matter which directory you’re on.
Well completion-ignore-case is enough to solve this particular problem, the other options are just sugar on top :)
I’m going to add completion-prefix-display-length to these related bonus tips (I have it set to 9). This makes it a lot easier to compare files with long names in your tab completion.
For example if you have a folder with these files:
FoobarSystem-v20.69.11-CrashLog2022-12-22 FoobarSystem-v20.69.11.config FoobarSystem-v20.69.12 FoobarSystem-v20.69.12-CrashLog2023-10-02 FoobarSystem-v20.69.12.config FoobarSystem-v20.69.12.userprofiles
Just type vim TAB to see
...1-CrashLog2022-12-22 ...1.config ...2 ...2-CrashLog2023-10-02 ...2.config ...2.userprofiles
$vim FoobarSystem-v20.69.1
GNU Readline (which is what Bash uses for input) has a lot of options (e.g. making it behave like vim), and your settings are also used in any other programs that use it for their CLI which is a nice bonus. The config file is ~/.inputrc and you’d enable the above mentioned options like this
$include /etc/inputrc
set completion-ignore-case on
set show-all-if-ambiguous on
set completion-map-case on
set completion-prefix-display-length 9
