proc_pid_comm(5)              File Formats Manual             proc_pid_comm(5)

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).
