Think the other way around: What’s the use case for case insensitive file names? Does it justify the effort and complexity for the filesystem and the programs to know the difference between lower and upper space chars?
What’s the use case for case insensitive file names?
Human comprehension.
Readme, readme, README, and ReadMe are not meaningfully different to the average user.
And for dorks like us - oh my god, tab completion, you know I mean Documents, just take the fucking d!
In case you or others reading this don’t know: You can set bash’s tab-completion to be case-insensitive by putting
set completion-ignore-case on
Into your .inputrc (or globally /etc/inputrc)
For some extra fun, try interop between two systems that treat this differently. Create a SMB share on a Linux host, create a folder named TEST from a Windows client, then make Test, tEst, teSt, tesT, and test. Put a few different files in each folder on the Linux side, then try to manage ANY of it from the Windows client
