Question

When navigating a file hierarchy under Cygwin, pressing tab after cd + a few characters will replace those few characters by the name of a directory whose name starts by the same characters, if such a directory is present in the current folder.
However, the test seems to be case-sensitive. How to deactivate the case-sensitivity ?

Answer 1

Try:

 set completion-ignore-case On

(This is for bash, which I’m pretty sure cygwin uses.)

EDIT:
This change will only take effect for the duration of your current shell session. To make it permanent, you need to add that line to your ~/.inputrc file.
