Try:
nawk '/interface/&&/move-group/{if(s)print s; s=x; n=2} n-->0{s=s $0 ORS} /filter-shared 14/{s=x; n=0} END{if(s)print s}' file

Relatively easy in sed:sed -n '

Hi.

This longish post is intended to show a general technique for working with paragraphs or stanzas of data. Each stanza is transformed so that a copy of it becomes a single, standard text line,...

One way with awk:
awk '/^interface/{print x}1' file |
awk '!/filter-shared 14/ && $1~/move-group/{print $1}' FS='\n' RS=

Does it have to be AWK? Try this if not:perl -ln0e 'while (/(interface[^\n]+).*?(?=interface|$)/sg){$x=$&;$y=$1;print $y if $x!~/filter-shared 14/ && $y=~/move-group/}' file

Nice work, I've seen many posts here asking for something similar so I know others will find this useful.

The 600 sec timeout is a little long - do you encounter issues with some commands taking a...

awk '{y=x;x=$0}y~/bridge1483/&&x!~/description/{print " ip description blabla..."}1' infile

Try

$ awk '/encapsulation bridge1483/{print;getline;if($0!~/ip description/)print "ip description blah_blah_blah"}1' fileinterface atm 1/0.190158 point-to-point

I don't review the logic with better arithmetic, I just provide the same function for shorter script as same as in your code

cat test.sh

echo $1|awk '{if ($5=="24") print $1,$2,$3, "0/24"
...

Nice solution RudiC !

I think it would be better to separate the fields in the index to avoid overflow between ranges.
I made an adaptation to your solution so that the CIDR prefix becomes...

Your sample output is not correct!

Tryawk '{if (++C[$1$2($3-$3%8)] == 8) print $1,$2,($3-$3%8),$4}' FS="." OFS="." file
10.71.192.0
10.122.232.0

Try the new version and use nawk instead of awk.

You can try to redirect the output to:
