From 2fc67e71af142bfa1e7662a4fde361f43509d2d7 Mon Sep 17 00:00:00 2001 From: Shenghou Ma Date: Sun, 1 Nov 2015 04:18:58 -0500 Subject: os: add Executable() (string, error) // Executable returns the path name for the executable that started // the current process. There is no guarantee that the path is still // pointing to the correct executable. If a symlink was used to start // the process, depending on the operating system, the result might // be the symlink or the path it pointed to. If a stable result is // needed, path/filepath.EvalSymlinks might help. // // Executable returns an absolute path unless an error occurred. // // The main use case is finding resources located relative to an // executable. // // Executable is not supported on nacl or OpenBSD (unless procfs is // mounted.) func Executable() (string, error) { return executable() } Fixes #12773.
