Hi Alain,

Thanks for the response. However it throws an error. Please find
below.

>>> from subprocess import *
>>> p1=Popen('/usr/sunvts/bin/64/vtsk -d',stdout=PIPE)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.4/subprocess.py", line 543, in __init__
    errread, errwrite)
  File "/usr/lib/python2.4/subprocess.py", line 975, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Thanks,
~Ashok.
