NAME

   /proc/pid/comm - command name

DESCRIPTION

   /proc/pid/comm (since Linux 2.6.33)
          This  file exposes the process's comm valuethat is, the command name associated with the process.  Different threads in the same process may have different comm values, acces
          sible 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).
