Hi xujian,

I didn't know Alcatel is also (still) using ClearCase ;-)

Re. the problem:

The sort order is dependent on your locale setting.
E.g. with LC_ALL=C, the result will be as you expected
while with LC_ALL=en_US.UTF-8, the result is the one you
got.

  $ LANG=C src/sort /tmp/x
  /VOBS/MediaGW/gw/src/cha
  /VOBS/MediaGW/gw/src/cha
  /VOBS/MediaGW/gw/src/cha
  /VOBS/MediaGW/gw/src/cha
  /VOBS/MediaGW/gw/src/res
  /VOBS/MediaGW/gw/src/res
  /VOBS/MediaGW/gw/src@@/m
  /VOBS/MediaGW/gw/src@@/m
  /VOBS/MediaGW/gw/src@@/m

More on this:

Therefore, I'm marking this bug as done.

Have a nice day,
