| Dec 10, 2020 at 2:17 | comment | added | TheTechRobo | @wizzwizz4 I get the same issue as @ScottF, and with your command: ❯ echo c | sudo tee /proc/sysrq-trigger and get the output tee: /proc/sysrq-trigger: Permission denied | |
| Aug 10, 2020 at 19:55 | comment | added | wizzwizz4 | @ScottF Try echo c | sudo tee /proc/sysrq-trigger. | |
| Aug 4, 2020 at 19:18 | comment | added | Maya | @ScottF are you really root, or are you using sudo? Note that sudo doesn't behave as you'd expect with redirections - the echo itself runs as root, but the output is redirected as your user. | |

| Apr 24, 2014 at 13:35 | comment | added | mykhal | how in OpenBSD? | |
| Mar 19, 2014 at 8:16 | comment | added | Christian | On Linux, you might have to echo 1 > /proc/sys/kernel/sysrq before you are able to echo c > /proc/sysrq-trigger. | |

| Feb 27, 2013 at 0:01 | comment | added | Desmond Hume | echo c > /proc/sysrq-trigger sure does a good job in freezing a Linux system. But personally, an ol' good black screen of death narrating about a dramatic development of the call stack would feel like a more "canonical" kernel panic. | |
