for some reason this didn't work...
Code:
[HelloWorld@localhost Junkiez]$ ls
test2 test2.cpp test.C
[HelloWorld@localhost Junkiez]$ test2
bash: test2: command not found
[HelloWorld@localhost Junkiez]$ test2
bash: test2: command not found
This way worked when I use a remote server with linux environment though...

it's weird, but i'm just wondering if anybody know what is the potential problem..?
