How to display detailed diagnostics and patch levels

Displaying detailed diagnostics of a Solaris machine:

admin@galactus$ /usr/platform/`uname -i`/sbin/prtdiag -v

WARNING The output of the command above is long -- make sure you pipe into a text pager (such as less or more) and/or redirect the output to a file.

Displaying all installed patches on a given machine:

admin@galactus$ showrev -p

Use man showrev for more information.

As above, the output is rather long, so make sure you pipe it into a grep, and then into a pager, for instance.

Displaying the Solaris release:

admin@galactus$ cat /etc/release

Hope this helps...
