Still no result:
Traceback (most recent call last): 2-1
NameError: name 'os' is not defined
THERE WAS AN ERROR LOADING THE SAGE LIBRARIES. Try starting Sage from

I tried to evaluate .py file from the command line under pool account:

print "b12"
os.chdir("/home/sageadm/sagenbfiles/worksheets/salsa/1/cells/11")

print _support_.syseval(sh, ur'''ls''',
'/home/sageadm/sagenbfiles/worksheets/salsa/1/cells/11')
print "e12"

[sage...@sagenb ~]$ sage -python

Something might have changed since Dan Drake wrote his notes on the
