Sorry, this is wrong. It has been changed between SUSV4 and SUSV3.
Now pwd
must not change $PWD. (It would be really nice to have SUSV4 man
pages...)
There are susv4 web pages which you can download and pull up with
"links" or similar if it really bothers you.
Trying to beat sane behavior out of bash is not a fruitful endeavor:
cd
mkdir missing
cd missing
rmdir ../missing
pwd -P
cd ..
ls
echo $PWD
I'm not copying that behavior.
