NAME

       /proc/pid/environ - initial environment

DESCRIPTION

       /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).
