Par défaut one liner sed or awk
hello everyone.
I have the following ifconfig output on solaris and want to be able to
get the output from it in the following format using a one liner.

ce0 192.168.13.50
ce0:1 192.168.13.245
ce0:2 192.168.13.64
ce0:3 192.168.13.62
ce1 192.168.13.51

bash-2.05$ ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index
3
inet 127.0.0.1 netmask ff000000
ce0:
flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRE CATED,IPv4,NOFAILOVER>
mtu 1500 index 4
inet 192.168.13.50 netmask fffffc00 broadcast 192.168.15.255
groupname amazon_ipmp_bk
ce0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500
index 4
inet 192.168.13.245 netmask fffffc00 broadcast 192.168.15.255
ce0:2: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index

inet 192.168.13.64 netmask fffffc00 broadcast 192.168.15.255
ce0:3: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index
4
inet 192.168.13.62 netmask fffffc00 broadcast 192.168.15.255
ce1:
flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRE CATED,IPv4,NOFAILOVER>
mtu 1500 index 5
inet 192.168.13.51 netmask fffffc00 broadcast 192.168.15.255

It's hard to tell how much of the formatting above is due to
linewrapping in your posting, but try this:

awk 'key ~ /^c/{print key,$2} {key = sub(/:$/,"",$1) ? $1 : ""}'

ifconfig -a |
sed -n 'h;s/^\([^ ]*\):.*/\1/p;g;s/.*inet \([^ ]*\).*/\1/p'

awk has better formatting capabilities:

ifconfig -a |
awk '$1~/:$/ {s=$1} {for(i=1;i<NF;++i) if($i=="inet") print s,$(i+1)}'

printf "%s\t%s\n",substr(s,1,length(s)-1),$(i+1)

formats the output as TAB-separated, and the substr() eliminates the
trailing :

Each interface has got 2 or more lines actually.
Consecutive lines are indented.

The question would fit better for comp.unix.admin or comp.unix.solaris

from the dirty tricks department:

ifconfig -a \
awk '/flags/ {sub(":$","",$1);f=$1;} /inet/ {printf ("%s\t%s\n",f,$2)}'


Note: This will generate a separate, full, line for each address assigned to
an interface with multiple addresses.
