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).
