Use the pkg search command to search for packages whose data matches the
specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages.
While the pkg contents command returns the contents, the pkg search command returns the
names of packages that match the query.

OpenBoot firmware is executed immediately after you turn on your system. The primary tasks of OpenBoot firmware are to:
*Test and initialize the system hardware (B)
*Determine the hardware configuration
*Boot the operating system from either a mass storage device or from a network (C)
*Provide interactive debugging facilities for testing hardware and software

Explanation:
A: In contrast to the SVR4 packaging model used in earlier Oracle Solaris releases, IPS eliminates the need for patching.

First line (rm file1) deletes/removes file1.
Second line captures the text into file2.
The first part of line 3 (cat file1) fails as the file1 does not exist.
The && (AND) operator will ensure that the third line fails.The result of line 3 will be the result of
first part of line 3 (cat file1).
Note: cat - concatenate files and print on the standard output
Note #1: A list is a sequence of one or more pipelines separated by one of the operators ';', '&',
'&&', or '||', and optionally terminated by one of ';', '&', or a newline.
Of these list operators, '&&' and '||' have equal precedence, followed by ';' and '&', which have
equal precedence.
AND and OR lists are sequences of one or more pipelines separated by the control operators '&&'
and '||', respectively. AND and OR lists are executed with left associativity.
An AND list has the form
command1 && command2
command2 is executed if, and only if, command1 returns an exit status of zero.
An OR list has the form
command1 || command2
command2 is executed if, and only if, command1 returns a non-zero exit status.
The return status of AND and OR lists is the exit status of the last command executed in the list.
Note #2 (on exit status): Zero means command executed successfully, if exit status returns non-
zero value then your command failed to execute.
