The Solaris operating environment sysdef utility outputs the current system definition in tabular form. It lists:
All hardware devices
Pseudo devices
System devices
Loadable modules
Values of selected kernel tunable parameters
This command generates the output by analyzing the named bootable operating system file (namelist) and extracting configuration information from it. The default system namelist is /dev/kmem.
For command syntax, options, and examples, see the sysdef man page.
