<br>
I installed a Python2.7 on my home directory in a Redhat Linux system.<br>
Then I tried to get rid of the system default path to python at<br>
'/usr/bin' --- I did this by set PATH="" in my .cshrc script. After I<br>
did a fresh system login, I find that my $PATH is set to empty.<br>
However, when I type "which<br>
python", I still get the old path "/usr/bin/python".<br>
<br>
I also tried set the evironment variable "set<br>
PYTHONPATH=/my_python_directory" in .cshrc and refresh my login, but<br>
the python command still refers to "/usr/bin/python".<br>
<br>
I just want to *overwrite* the system build-in python with my own<br>
installation, could anybody tell me how can I do that?<br>
<br>
Many thanks!<br>
Leo<br>
