Set shell environment variables from within Golang script?

[Victor Hooi]

Hi,

Is there a way to edit the user's environment variables from within a Go script, so that they persist when the Go program finishes execution?

We're using this to modify the user's PATH variable to control which version of a program is being run. (Alternatives would be messing around with symlinks or just mv-ing files around, however, the PATH seems like a lighter and less messy way of doing it).

Is this possible from Golang at all?

Cheers,

Victor

That's not doable in any programming language because there's no way to change parent's environment variable from child process.

You can print out something like this from a command

  export PATH=/foo/bar:$PATH

and then evaluate the output in a shell using `` to change the shell's environment variable, but that's different from changing parent's environment from child.
