C: Here the wildcard character ? is used (Matches any single character).
file1 and file2 will be copied into dir1
F: the two files file1 and file2 are copied into directoy dir1.
Note: cp - copy files and directories
Copy SOURCE to DEST,or multiple SOURCE(s) to DIRECTORY.
Cp has three principal modes of operation. These modes are inferred from the type and count of arguments presented to the program upon invocation.
*When the program has two arguments of path names to files,the program copies the contents of the first file to the second file,creating the second file if necessary.
*When the program has one or more arguments of path names of files and following those an argument of a path to a directory,then the program copies each source file to the destination directory,creating any files not already existing.
*When the program's arguments are the path names to two directories,cp copies all files in the source directory to the destination directory,creating any files or directories needed. This mode of operation requires an additional option flag,typically r,to indicate the recursive copying of directories. If the destination directory already exists,the source is copied into the destination,while a new directory is created if the destination does not exist.

The zfs list command provides an extensible mechanism for viewing and querying dataset information.
You can list basic dataset information by using the zfs list command with no options. This command displays the names of all datasets on the system and the values of their used, available, referenced, and mountpoint properties. For more information about these properties, see Introducing ZFS Properties.
For example:
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
pool 476K 16.5G 21K /pool
pool/clone 18K 16.5G 18K /pool/clone
pool/home 296K 16.5G 19K /pool/home
pool/home/marks 277K 16.5G 277K /pool/home/marks
pool/home/marks@snap 0 - 277K -
pool/test 18K 16.5G 18K /test

On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process. Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files. For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

Explanation:
The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite.
ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute).
