Problem discovered in tr (GNU coreutils) 8.13 on a Ubuntu 12.04.

Running those commands:

cd $HOME
echo "Linux" | tr [:upper:] [:lower:]

will result: linux

Running the same from /usr/bin:

cd /usr/bin
echo "Linux" | tr [:upper:] [:lower:]

will result: winux
which is obviously a bad answer.

In debug mode:

sh -xc "echo "Linux" | tr [:upper:] [:lower:]"
+ echo Linux
+ tr [:upper:] w
winux

Regards.

Underquoted.  Run:

echo [:upper:] [:lower:]

and then

echo "[:upper:]" "[:lower:]"

in the two directories to spot the difference.  (Hint - in one of your
two directories, a shell glob is matching a one-byte file name)

As this is user error and not a bug in tr, I'm marking this bug as
closed, but feel free to add more comments if you still need help
understanding the issue.
