Scissors Grep multiple pattern
I have got a text
from each line, I need to fetch port only if there is an ip

Code:
a.text text  and port=25
b.ip=(12.32.54.256) and port="52"
c.ip=(55.251.253.12) and port=25"
d.text text and port="5"
e.ip=(45.211.155.15) and port="457"
f.ip=(144.158.256.2) and port="588"

I know how to fetch ip per line:
Code:
awk 'BEGIN{ RS="<\n>"}1' file | grep -oP "(?<=ip=\()[^)]*"

(well in this case, awk is not very usefull, but in the actual file, it is)

I know how to grab ports individually:

Code:
grep -oP "(?<=port=\")[^\"]*" file

but I do not know how to grab both and only both (line a and d should not be in the output)

Thanx in advance folks!

rsdwnlnk

RSDWNLNK(8)						     Linux Programmer's Manual						       RSDWNLNK(8)

NAME

       rsdwnlnk - User exit from the ROSE network.

SYNOPSIS

       rsdwnlnk <port> <call>

DESCRIPTION

       The  rdwnplnk  program allows a user to leave the ROSE network using the standard pseudo-digipeating method. Recent Linux kernels are aware
       of this form of operation and the ax25d program can create such connections. The normal mode of operation of a ROSE switch is to  have  one
       ROSE  address (ie port) per physical AX.25 port.  Therefore ROSE users coming in on a given ROSE port will come out of the associated AX.25
       port.

       To use rsdwnlnk you need an entry in ax25d.conf to listen for incoming ROSE connections to any callsigns that are not matched by  the  more
       specific  ROSE  entries. In the example below, I will be listening for ROSE connections on my ROSE port rs144, the exiting AX.25 connection
       will be via the associated AX.25 port, 144, using the callsign KE4GAJ-10. Please note that the callsign should be on the same line  as  the
       rest of the command, it may be wrapped onto the next line on your screen.

       #
       {* VIA rs144}
       NOCALL  * * * * * * L
       default * * * * * * - root /usr/sbin/rsdwnlnk rsdwnlnk 144 KE4GAJ-10
       #

       There would typically be one rsdwnlnk per ROSE port. The associated program for entering a ROSE network is rsuplnk.

       All errors generated by rsdwnlnk are written to the system debug log file.

FILES

       /etc/ax25/axports
