写入/proc/sysrq-trigger中的字符其实就是sysrq.txt中说的键所对应的字符,其功能也和上述一样。 所以,这两行命令先开启SysRq功能,然后用'b'命令让计算机立刻重启。 /proc/sysrq-trigger该文件能做些什么事情呢? # 立即重新启动计算机 (Reboots the kernel without first unmounting file systems or syncing dis...
* b - 即时重新启动系统, * o - 即时关机(如果机器设置并支持此项功能)。
66 'b' - Will immediately reboot the system without syncing or unmounting 67 your disks. 68 69 'c' - Will perform a system crash by a NULL pointer dereference. # 立即重新启动计算机 echo "b" > /proc/sysrq-trigger # 立即关闭计算机 echo "o" > /proc/sysrq-trigger # 导出内存分配的信息...

但有一些是共用的:* m - 导出关于内存分配的信息* t - 导出线程状态信息* p - 到处当前CPU寄存器信息和标志位的信息* c - 故意让系统崩溃(在使用netdump或者diskdump的时候有用)* s - 立即同步所有挂载的文件系统* u - 立即重新挂载所有的文件系统为只读* b - 立即重新启动系统* o - 立即...

On the other hand, assuming that you have a root shell open already, echo b > /proc/sysrq-trigger does not need any filesystem access. 简而言之,echo "b" > /proc/sysrq-trigger 可以确保环境在挂文件系统的时候重启成功;
