       /proc/sysrq-trigger - SysRq function

DESCRIPTION
       /proc/sysrq-trigger (since Linux 2.4.21)
              Writing a character to this file triggers the same SysRq
              function as typing ALT-SysRq-<character> (see the description of
              /proc/sys/kernel/sysrq).  This file is normally writable only by
              root.  For further details see the Linux kernel source file
              Documentation/admin-guide/sysrq.rst (or Documentation/sysrq.txt
              before Linux 4.10).
