Is there a way to overload operators like '>' and '>>' in bash, just as overloading in C++, etc. Suppose I have already made some bash program using '>' and '>>' without thinking about symbolic link, but I begin aware of them later. I would be cumbersome to add a test statement and deciding whether 'rm' or not for each usage of '>' and '>>'. A more general question is how to change the behavior of a program (for example compiled from C code) to delete symbolic link and write a new file, without recompiling the program. -- Regards, Peng
