Golang：Chdir，并在程序终止时留在那里

Question

In golang (as well as bash scripting) if I change the current working directory (with os.Chdir) it works, but when the program terminates the working directory gets reset to the location it had when the program started.

It makes sense, but what I want to do is an inteligent disk navigator (something like our old and beloved ncd, "Norton Change Directory").

How can I tell the binary (or the shell that starts it, or whatever) not to reset to the previous working path?

I would like to achieve that entirely from within the Go binary, without modifying .bashrc or .zshrc (for portability)

Answer 1

The working directory of every process is process-private.

You'll have to jump loops to achieve this. For example, your program can write a script (file), which can be executed later, after you program terminates, from a script, which invoked your program.

Another, less hacky method is:

$ cd $(prog)

where prog writes the new wd to stdout.
