rm -rf /proc/cygdrive/?/today/tmp

But I advise against such wildcards, as these drives could be inaccessible,
locking you out of console for hours.

Also, cygwin ignores device type field when mounting paths. Effectively, you
could use "bind", which is closer to what actually happens.

>> # /etc/fstab

>> # This is default anyway:
>> #none /cygdrive cygdrive binary,posix=0,user 0 0
>> none /mnt cygdrive noacl,binary,nouser,posix=0 0 0
>> W:/ /run bind acl,binary,nouser,posix=0 0 0
>> none /tmp usertemp binary,user,posix=0 0 0

Also, I would strongly advise against what you are doing (Re: your other
reply).
Specifying "C:" instead of "C:\" (or, well, "C:/", which is synonymous)
introduces ambiguity. Drive specification without a path points to "current
path" on a specified drive. Which is not necessarily a root path.
