insmod [filename] [module options ...]
insmod is a trivial program to insert a module into the kernel: if the filename is a hyphen, the module is taken from standard input. Most users will want to use modprobe(8) instead, which is cleverer.
Only the most general of error messages are reported: as the work of trying to link the module is now done inside the kernel, the dmesg usually gives more information about errors.
This version of insmod is for kernels 2.5.48 and above. If it detects a kernel with support for old-style modules (for which much of the work was done in userspace), it will attempt to run insmod.old in its place, so it is completely transparent to the user.
