NAME

       /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).
