The usual method (afaik) is to use relative paths, and to not change into the script dirs before running them. eg, instead of: cd src/dir1/dir2/dir3 ./script.py You run it like this: ./src/dir1/dir2/dir3/script.py And then all the scripts under src can load data files using a path like this: './data/datafile' Another method is to use a file-finder func which looks in various places (using PATH, PYHONPATH, etc), and returns the first-found path to the file. -- http://mail.python.org/mailman/listinfo/python-list
