Please give your inputs !!!!
I am trying to extract two fields from the output of ifconfig command on one of my sun server . The output looks like :
root@e08k18:/tmp/test# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 10.177.4.61 netmask ffffff00 broadcast 10.177.4.255
groupname ipmp0
ether 0:3:ba:6c:7f:2e
I require output as field1 filed2 for all the interfaces ...but when I try
la0 127.0.01
ce0 10.177.4.61
# ifconfig |awk -F ":" {print $1 $3)'
However I am not getting the required output.
Any clue in this regard will be of great help.
Thanking you in advance.

ifconfig.if
IFCONFIG.IF(5) BSD File Formats Manual IFCONFIG.IF(5)
NAME
ifconfig.if -- interface-specific configuration files or variables
DESCRIPTION
The ifconfig.if files or variables contain information regarding the configuration of each network interface. ifconfig.if is processed by
/etc/rc.d/network at system boot time.
For each interface (nnX) that is to be configured, there should be either an ifconfig_nnX variable in rc.conf(5), or an /etc/ifconfig.nnX
file (such as the ifconfig_fxp0 variable or the /etc/ifconfig.fxp0 file for the fxp0 interface). Only characters allowed in sh(1) variables
names should be used for nnX (ascii(7) uppercase and lowercase letters, digits, and underscore).
The variable or file will get evaluated only if the interface exists on the system. Multiple lines can be placed in a variable or file, and
will be evaluated sequentially. In the case of a variable, semicolons may be used instead of newlines, as described in rc.conf(5).
<backslash><newline> sequences in files are ignored, so long logical lines may be made up of several shorter physical lines.
Normally, a line will be evaluated as command line arguments to ifconfig(8). ``ifconfig nnX'' will be prepended on evaluation. Arguments
with embedded shell metacharacters should be quoted in sh(1) style.
If the line is equal to ``dhcp'', dhcpcd(8) will be started for the interface. However, it is instead recommended that dhcpcd is set to true
in rc.conf(5) and any per interface configuration or restriction is done in dhcpcd.conf(5).
If a line is empty, or starts with '#', the line will be ignored as comment.
If a line starts with '!', the rest of line will get evaluated as shell script fragment. Shell variables declared in /etc/rc.d/network are
accessible but may not be modified. The most useful variable is $int, as it will be bound to the interface being configured with the file.
For example, the following illustrates static interface configuration:
# IPv4, with an alias
inet 10.0.1.12 netmask 255.255.255.0 media 100baseTX
inet 10.0.1.13 netmask 255.255.255.255 alias
# let us have IPv6 address on this interface
inet6 2001:db8::1 prefixlen 64 alias
# have subnet router anycast address too
inet6 2001:db8:: prefixlen 64 alias anycast
The following illustrates dynamic configuration setup with dhclient(8) and rtsol(8):
up
# autoconfigure IPv4 address
!dhclient $int
# autoconfigure IPv6 address. Be sure to set $ip6mode to autohost.
!rtsol $int
The following example sets a network name for a wireless interface (using quotes to protect special characters in the name), and starts
dhcpcd(8):
ssid 'my network'
dhcp
The following example is for dynamically-created pseudo interfaces like gif(4). Earlier versions of /etc/rc.d/network required an explicit
'create' command for such interfaces, but creation is now handled automatically.
up
# configure IPv6 default route toward the interface
!route add -inet6 default ::1
!route change -inet6 default -ifp $int
