How to make my alpine linux case insensitive for cd MyFolder and cd myfolder

Hi,

I want to make sure that when I use cd “directoryname”. the directory name should be case insenstive.

cd directoryname and cd DirectoryName should give me the correct answer.

I saw this example.

# If ~/.inputrc doesn't exist yet: First include the original /etc/inputrc
# so it won't get overriden
if [ ! -a ~/.inputrc ]; then echo '$include /etc/inputrc' > ~/.inputrc; fi

# Add shell-option to ~/.inputrc to enable case-insensitive tab completion
echo 'set completion-ignore-case On' >> ~/.inputrc

I put this in a .sh file and call RUN sh ./CaseInsensitive.sh

sh: /root/.inputrc: unknown operand

If this question is answered please direct me to the correct thread.

Thanks a bunch.
