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).
