Note

The file /proc//environ contains the initial environment that was set when the currently executing program was started via execve(2). If, after an execve(2), the process modifies its environment (e.g., by calling functions such as putenv(3) or modifying the environ(7) variable directly), this file will not reflect those changes—see proc(5) for futher informations.
