NAME

       /proc/pid/cmdline - command line

DESCRIPTION

       /proc/pid/cmdline
              This  read-only  file  holds  the  complete  command line for the process, unless the process is a
              zombie.  In the latter case, there is nothing in this file: that is, a  read  on  this  file  will
              return 0 characters.

              For  processes which are still running, the command-line arguments appear in this file in the same
              layout as they do in process memory: If the process is  well-behaved,  it  is  a  set  of  strings
              separated by null bytes ('\0'), with a further null byte after the last string.

              This  is  the  common case, but processes have the freedom to override the memory region and break
              assumptions about the contents or format of the /proc/pid/cmdline file.

              If, after an execve(2), the process modifies its argv strings, those changes will  show  up  here.
              This is not the same thing as modifying the argv array.

              Furthermore,  a  process  may  change  the  memory  location  that  this  file refers via prctl(2)
              operations such as PR_SET_MM_ARG_START.

              Think of this file as the command line that the process wants you to see.
