推荐答案

在Linux上，符号链接/proc/<pid>/exe具有可执行文件的路径.使用命令readlink -f /proc/<pid>/exe来获取值.

On Linux, the symlink /proc/<pid>/exe has the path of the executable. Use the command readlink -f /proc/<pid>/exe to get the value.

在AIX上，此文件不存在.您可以比较cksum <actual path to binary>和cksum /proc/<pid>/object/a.out.

On AIX, this file does not exist. You could compare cksum <actual path to binary> and cksum /proc/<pid>/object/a.out.
