proc_pid_environ(5) File Formats Manual proc_pid_environ(5)
/proc/pid/environ - initial environment
/proc/pid/environ
This file contains the initial environment that was set
when the currently executing program was started via
execve(2). The entries are separated by null bytes
('\0'), and there may be a null byte at the end. Thus, to
print out the environment of process 1, you would do:
$ cat /proc/1/environ | tr '\000' '\n'
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.
Furthermore, a process may change the memory location that
this file refers via prctl(2) operations such as
PR_SET_MM_ENV_START.
Permission to access this file is governed by a ptrace
access mode PTRACE_MODE_READ_FSCREDS check; see ptrace(2).
