Re: Sed advice needed
Here's one way:
# Put the sample lines into a file called inline.txt
for inline in `cat inline.txt | tr -d " "` #remove spaces for cut
do
# Remove quotes
Tmp=`echo $inline | tr -d "\""`
# Break into fields...
f1=`echo $Tmp | cut -f1 -d","`
f2=`echo $Tmp | cut -f2 -d","`
f3=`echo $Tmp | cut -f3 -d","`
f4=`echo $Tmp | cut -f4 -d","`
f5=`echo $Tmp | cut -f5 -d","`
# Get data past = char form the 3rd entry in 6th field
f6=`echo $Tmp | cut -f8 -d"," | cut -f2 -d"="`
echo "\"$f1\",\"$f2\",\"$f3\",\"$f4\",\"$f5\",\"$f6\""
done
Enjoy,
Larry

Subject: Sed advice needed
Hello all,
I need to delete some words out of a large file containing information
about packets I'm analysing. I know I can use sed to do this, but
haven't really used it before, so am a bit unsure of how to do it. Two
example lines are as of below:
"181","1324.014027","111.111.111.111","111.111.111.111","RTP","Payload t
ype=ITU-T H.261, SSRC=2008229573, Seq=54520, Time=1725612773, Mark"
"185","1324.078941","111.111.111.111","111.111.111.111","RTP","Payload t
ype=ITU-T H.261, SSRC=2008229573, Seq=54521, Time=1725616276"
I need to convert the above to the below:
"181","1324.014027","111.111.111.111","111.111.111.111","RTP","54520"
"185","1324.078941","111.111.111.111","111.111.111.111","RTP","54521"
What's the best way to do this? I've been reading the man pages of sed,
cut and awk but I can't quite figure out how to do this. Any ideas?
Thanks very much for your time in advance!
Regards - Piers
