History
 NAME
history - command history
 SYNOPSIS
history [limit]
 DESCRIPTION
Since many of the programs read user input a line at a time, the command history is used to keep track of these
lines and also recall historic information
 HISTORY NAVIGATION
The command history can be navigated using the up and down arrow keys. The up arrow will move up a single
entry in the command history while the down arrow moves down in the command history.
 HISTORY EXPANSION
The command history supports the expansion functionality from which previous commands can be recalled from
within a single session. History expansion is performed immediately after a complete line is read.
Listed below are examples of history expansion:
* !! Subsitute the the last command line.
* !N Substitute the Nth command line (absolute as per ’history’ command)
* !-N Substitute the command line entered N lines before (relative)
 EXAMPLES
history
Displays the current command buffer
history 5
Sets the history command buffer to remember the last 5 unique entries
Network Ping
 NAME
network ping - send ICMP ECHO_REQUEST to network hosts
 SYNOPSIS
network ping [count <count>] [size <size>] <destination-ip>
 DESCRIPTION
Use the ICMP protocol’s mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE
from a host or gateway. ECHO_REQUEST datagrams have an IP and ICMP header, followed by a struct timeval
and then an arbitrary number of pad bytes used to fill out the packet.
 OPTIONS
count Stop after sending count ECHO_REQUEST packets. With deadline option, ping waits for count
ECHO_REPLY packets, until the timeout expires. The default is 5.
destination
The destination IP address where the ECHO_REQUESTS are sent
size The data size of the ICMP packet to send. The default is 56 bytes
 EXAMPLES
network ping 192.168.1.1
Attempt to send 5 ICMP ECHO_REQUESTs with data size 56 to the host at 192.168.1.1
network ping count 10 size 100 192.168.1.1
Attempt to send 10 ICMP ECHO_REQUESTs with data size of 100 to the host at 192.168.1.1
