NAME
/proc/pid/comm - command name
DESCRIPTION
- /proc/pid/comm (since Linux 2.6.33)
-
This file exposes the process's
comm
value[em]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).
