Case sensitivity is something you do adjust to over time.

Saying "Linux is case-sensitive" is a bit simplistic. In the case of Linux and
other UNIX systems, case sensitivity is a function of the underlying
filesystems provided by the kernel.

This might not be the case for OS/2 where I suspect the case insensitivity is
in a layer above the IFS drivers.

Programatically it's easier to write case-insensitive filesystem drivers
because case insensitivity depends on which language you are using, unless of
course the drivers assume English and map 'a'..'z' to 'A'..'Z' and nothing
more.

Linux's cousin, OS X, uses the HFS filesystem which by default
case-insensitive. Typing "curl" or "CURL" or "cUrL" in OS X's Terminal will run
 the same command.

The arguments are still case sensitive, though! "curl -d" and "CURL -D" will do
 different things.

Conceivably you could run a Linux distro from a case-insensitive filesystem,
eg. JFS created with "mkfs.jfs -O". It would be an interesting experiment.

Alternatively you could have a separate home partition formatted with "mkfs.jfs
 -O" and have the rest of the system use the default ext4.

ZFS pools can also be set to be case-insensitive.
