ECHO
NAME:
echo
- display a line of text or an environment variable's value
SYNOPSIS:
echo [OPTION]... [STRING]...
DESCRIPTION:
echo displays a line of text, or an environment variable's value. Notice that "ls"
command is not supported in the CLI. Echo can be used to display files and
subdirectories using wildcard '*'.
COMMANDS:
None.
OPTIONS:
-n
suppress trailing newline
-e
interpret backslash-escaped characters (i.e., \t=tab)
-E
disable interpretation of backslash-escaped characters
EXAMPLES:
Display a string
echo "Hello, world"
Display the vaule of the environment variable $TERM
echo $TERM

IFCONFIG
NAME:
ifconfig
- configure a network interface
SYNOPSIS:
ifconfig [interface]
ifconfig interface [aftype] options | address ...
DESCRIPTION:
Ifconfig is used to configure the kernel-resident network interfaces. It is used
at boot time to set up interfaces as necessary. After that, it is usually only
needed when debugging or when system tuning is needed. I f no arguments
are given, ifconfig displays the status of the currently active interfaces. If a
single interface argument is given, it displays the status of the given interface
only; if a single -a argument is given, it displays the status of all interfaces,
even those that are down. Otherwise, it configures an interface.
COMMANDS:
None.
OPTIONS:
interface
The name of the interface. This is usually a driver name followed by a
unit number, for example eth0 for the first Ethernet interface.
address
The IP address to be assigned to this interface.
Up
This flag causes the interface to be activated. It is implicitly specified if
an address is assigned to the interface.
down
This flag causes the driver for this interface to be shut down.
[-]arp
Enable or disable the use of the ARP protocol on this interface.
[-]promisc
Enable or disable the promiscuous mode of the interface. If selected, all
packets on the network will be received by the interface.
[-]allmulti
Enable or disable all-multicast mode. If selected, all multicast packets on
the network will be received by the interface.
metric N
This parameter sets the interface metric.
mtu N
This parameter sets the Maximum Transfer Unit (MTU) of an interface.

dstaddr addr
Set the remote IP address for a point-to-point link (such as PPP). This
keyword is now obsolete; use the pointopoint keyword instead.
netmask addr
Set the IP network mask for this interface. This value defaults to the
usual class A, B or C network mask (as derived from the interface IP
address), but it can be set to any value.
irq addr
Set the interrupt line used by this device. Not all devices can dynamically
change their IRQ setting.
io_addr addr
Set the start address in I/O space for this device.
mem_start addr
Set the start address for shared memory used by this device. Only a few
devices need this.
[-]broadcast [addr]
If the address argument is given, set the protocol broadcast address for
this interface. Otherwise, set (or clear) the IFF_BROADCAST flag for the
interface.
[-]pointopoint [addr]
This keyword enables the point-to-point mode of an interface, meaning
that it is a direct link between two machines with nobody else listening
on it. If the address argument is also given, set the protocol address of
the other side of the link, just like the obsolete dstaddr keyword does.
Otherwise, set or clear the IFF_POINTOPOINT flag for the interface.
[-]trailers
Set or clear the IFF_NOTRAILERS flag for the interface.
[-]dynamic
Set or clear the IFF_DYNAMIC flag for the interface.
hw class address
Set the hardware address of this interface, if the device driver supports
this operation. The keyword must be followed by the name of the
hardware class and the printable ASCII equivalent of the hardware
address. Hardware classes currently supported include ether (Ethernet)
only.
multicast
Set the multicast flag on the interface. This should not normally be
needed as the drivers set the flag correctly themselves.

outfill N
This parameter sets the interface outfill timeout.
keepalive N
This parameter sets the interface keepalive timeout.
txqueuelen length
Set the length of the transmit queue of the device. It is useful to set this
to small values for slower devices with a high latency (modem links,
ISDN) to prevent fast bulk transfers from disturbing interactive traffic
like telnet too much.
EXAMPLES:
Display all the active interfaces
ifconfig
Set interface eth0's IP address to be 192.168.1.1, netmask to be
255.255.255.0
ifconfig eth0 192.168.1.1 netmask 255.255.255.0
