hi all,

Le Saturday 15 October 2005 09:48, Anton Altaparmakov a =E9crit=A0:
 | If it has sysrq compiled in as root just do:
 |
 | echo s > /proc/sysrq-trigger
 | echo u > /proc/sysre-trigger
 | echo s > /proc/sysrq-trigger
 | echo b > /proc/sysrq-trigger
 |
 | This will "sync", "umount/remount read-only", "sync", "immediate
 | hardware reboot". =A0Should always work...

i'm impressed that i see that sysrq also works from procfs.... the=20
"PrintScreen/SysRq" button on my keyboard from time to time does not work=20
(old keyboard) and then it's pain hitting this key if you have to.=20

great news that you can also pass sysrq requests using proc - i've learned=
=20
something today... is this documented somewhere? maybe i'm bad in=20
reading/finding docs but i think i'm not the only one here. can somebody=20
point me to the links of docs where all this magic is specified? if not,=20
i will try to start my own docs on how to use the linux kernel magic.=20
mainly a collection of tricks like this and similar ones.=20

thank you in advance + greetings,
Damir

  Customer: (angrily) "You said I would get 98 windows with this computer.=
=20
Where are they?"=20
