命令

lsmod - Show status of modules in the Linux kernel.

lsmod is a trivial program which nicely formats the contents of the /proc/odules,
showing what kernel modules are currently loaded.
dmesg - examine or control the kernel ring buffer.

The kernel buffer is a data structure used for keeping the log messages of the kernel and the kernel modules.
It’s a ring buffer with a fixed size. Once it’s full, new messages overwrite the oldest messages.
During boot, the kernel saves the messages into the kernel buffer.
lsscsi - Uses information in sysfs (Linux kernel series 2.6 and later) to list SCSI devices (or hosts) currently attached to the system.
