Hi,
We found a bug of tr, the version is tr (coreutils) 5.2.1
Here is the symptom:
When there is a file named e or r under current directory, tr will take
effect,like:
echo hello |tr [a-z] [A-Z]
echo hello |tr [:lower:] [:upper:]
will return hello
And when is a file named l, o, p, u or w under current directory, tr will give
error message like:
echo hello |tr [a-z] [A-Z]
echo hello |tr [:lower:] [:upper:]
gives : tr: misaligned [:upper:] and/or [:lower:] construct
But if you try
echo kkhh |tr "[a-z]" "[A-Z]"
echo kkhh |tr "[:lower:]" "[:upper:]"
There will be no error and it takes effect.
Brs
