(?) The problem is, he is not printing the name of the current working directory; he is printing the value of the variable $PWD. That is likely set from the environment by the shell he started the Python program from, but Python does *not* update to reflect changes to the working directory. Use '@pwd' instead of '@echo $(PWD)'. -- Thomas Bellman, Lysator Computer Club, Linköping University, Sweden "Beware of bugs in the above code; I have ! bellman @ lysator.liu.se only proved it correct, not tried it." !
