NAME

       /proc/pid/comm - command name

DESCRIPTION

       /proc/pid/comm (since Linux 2.6.33)
              This  file exposes the process's comm value—that is, the command name associated with the process.
              Different  threads  in  the  same  process  may  have  different  comm  values,   accessible   via
              /proc/pid/task/tid/comm.   A  thread  may modify its comm value, or that of any of other thread in
              the same thread group (see the discussion of CLONE_THREAD in clone(2)), by  writing  to  the  file
              /proc/self/task/tid/comm.   Strings  longer  than  TASK_COMM_LEN  (16)  characters  (including the
              terminating null byte) are silently truncated.

              This file provides a superset of the prctl(2)  PR_SET_NAME  and  PR_GET_NAME  operations,  and  is
              employed by pthread_setname_np(3) when used to rename threads other than the caller.  The value in
              this file is used for the %e specifier in /proc/sys/kernel/core_pattern; see core(5).
