I am probably asking for too much of a miracle...

Actually, the command given above is wrong.
It should be either:

   echo `pwd` > pwd.txt

or (much better) just

  pwd > pwd.txt


the 'cat' command is used to output the contents of a file to the standard output. Using 'cat' with a directory name instead of a regular file name will yield an error.
