Something is wrong in the os then. The extra ../ just loops back on itself
until it runs out of ../'s. Or should, and I will take an example from a
1987 computer, a TRS-80 Color Computer 3 running nitros9, which is a very
unix like os and my teacher, the real reason I haven't had but one windows
machine over the years & that was only because I couldn't buy a laptop w/o
windows. Long since nuked of course.
Pasted from a minicom screen on this linux box:
{t2|08}/DD/NITROS9/6309L2/SCRIPTS:dir ../../../../../../nitros9
Directory of ../../../../../../nitros9 2012/10/20 21:48
6309L2 6309L3 3.2.9 COLORZAP.DSK HRSDOS.os9
DSKS 3.2.9a dw3install boottrack-gene DW-stf
dd.b09 DW3TREE cmds.os9 OS9Gen Cobbler
dsave.out
The drive is /dd, the system default. I am cd'd to a point 3 levels up from
the devices root directory. Note that I had enough ../'s in there to make
it back up 6 levels, but the 'dir' command worked just fine.
By the same token, it does NOT work that way on this linux box. We should
pester the kernel folks on lkml I believe. The point being that at the
root directory, the .. entry should point at itself since you can't back up
any farther.
