How to disable uppercase validation in autocompletion of cygwin folder?

Question

When navigating the file hierarchy under Cygwin, clicking on the tab after cd + a few characters replaces these several characters with the name of the directory whose name begins with the same characters, if such a directory is present in the current folder. However, the test seems to be case sensitive. How to deactivate case sensitivity?

Answer 1

to try

  set completion-ignore-case On 

(This is for bash, which I'm sure cygwin is using.)
