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
