vtkpython: command not found... why ? it is there..

hi,

I can't run the process vtkpython. I'm inside the bin directory and i can see the command

omhp-uva-21-43:bin aneuryzma$ ls -l
total 520
-rwxr-xr-x@ 1 aneuryzma  staff    2426 Aug 30  2005 Cone.py
-rwxr-xr-x  1 root       staff   26492 Sep  1 16:39 lproj
-rwxr-xr-x  1 root       staff   22708 Sep  1 16:39 vtkEncodeString
-rwxr-xr-x  1 root       staff  106536 Sep  1 16:37 vtkWrapPython
-rwxr-xr-x  1 root       staff   16868 Sep  1 16:37 vtkWrapPythonInit
-rwxr-xr-x  1 root       staff   73852 Sep  1 17:18 vtkpython

But if I launch it:

omhp-uva-21-43:bin aneuryzma$ sudo vtkpython Cone.py 
Password:
sudo: vtkpython: command not found

How is possible that is not found if it is there ? I'm in the same directory

thanks

most like your $PATH does not include current directory (.)
try:

sudo vtkpython ./Cone.py

or specify a full/relative path to a file.
