Luke Lu commented on HADOOP-6618:
---------------------------------
@Nicholas, if you make ^ as part of the escape characters in your patch, the [^
functionality would be broken.
BTW, glob pattern [! is defined by the POSIX standard, and [^ is actually
undefined (see above link for details). We can support both though.
> fs -ls does not work if a path name contains the ^ character
