Match 2 different patterns and print the lines
Hi,

i have been trying to extract multiple lines based on two different patterns as below:-

file1
Code:
@jkm|kdo|aas012|192.2.3.1 blablbalablablkabblablabla
sjfdsakfjladfjefhaghfagfkafagkjsghfalhfk
fhajkhfadjkhfalhflaffajkgfajkghfajkhgfkf
jahfjkhflkhalfdhfwearhahfl
@jkm|sdf|wud08q|168.2.1.3 bkblblblabdlablfbalflaflabfblaslfbalfblaf
gfrkqghfrkadegfeowfrkefewurfgefhjwavfss
gjgferjwgfrjewgfjrewgafrjgjwgrfjwgerjwg
we
@jkm|qpw|dgs901|192.2.45.3 blabslabdsa
ahfkghqewafroewforewfthewofghrwgh
whrgfrjwgflwgjh
@jkm|ppl|hfjsf87|192.2.3.8 bdfksfbdkbfdfbdgksdgbks
ksgfhglkshddlgsslghdlgh;lsdgj;sdkgs

I need to extract the ip address, for example: 192.2.3 and print all the lines start from "@" until it reaches the next "@" like below:-

output
Code:
@jkm|kdo|aas012|192.2.3.1 blablbalablablkabblablabla
sjfdsakfjladfjefhaghfagfkafagkjsghfalhfk
fhajkhfadjkhfalhflaffajkgfajkghfajkhgfkf
jahfjkhflkhalfdhfwearhahfl
@jkm|ppl|hfjsf87|192.2.3.8 bdfksfbdkbfdfbdgksdgbks
ksgfhglkshddlgsslghdlgh;lsdgj;sdkgs

for each line in bold (first line of each record), there is \n at the end.

the codes that i tried:-

Code:
awk '/^@/{p=0} /^@jkm/{p=1}p' file1

and tried to find and match 192.2.3. by grep and etc but did not get the right output. Can anyone tell me how to run two awk commands for implementing 2 different things one after another such as a case like this? I tried some that i found but none is successful. I am still trying my best to learn and understand awk and sed. Thanks

       -d    Display only the local domain's IP address.

       -s    Display only the remote Service Processor's IP address.

EXAMPLES

       Example 1 Displaying both addresses

       The following example displays both the local domain's IP address and the remote SP's IP address:

	 # prtdscp
	 Domain Address: 192.168.103.2
	 SP Address: 192.168.103.1

       Example 2 Displaying the local IP address

       The following example displays the local domain's IP address:
