Please use code tags next time for your code and data. Thanks
So you are going to end up with numerous error files in the form of:
{cname}_{statuscode}.err
Such as:
common_404.err
Is that what you mean?

If that is what you want, you can try the below code. It will read each line from your log file and insert it into its own error log file accordingly. It will build these error log files in the same directory as where you run the script.
Code:
#!/bin/ksh
while read -r line
do
echo ${line} >> $(echo ${line} | awk -F"[/ ]" '{print $10"_"$(NF-1)".err"}')
done < logfile
Thanks for you it seem to be working, but
1) I need to send status code 200 to 399 to all send to access log
2) I need to send status code 400 to 599 send to error log
So if the input file is considered as space separated, do you want each message sent to a file based on column 8 (they are all 404 in your example)
You could use less processing with:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$h
done < logfile
If you want to base it on the first bit of column 7 (the pl, uk or common bit) you need another tweak to split up to column:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
ref="${g#/}" # Trim off leading /
ref="${ref%%/*}" # Trim off everything after the first /
echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$ref
done < logfile
Of course, you could use both if you with, so your output file will become /path/to/file-$ref-$h or whatever.
If you have codes in column 8 that are errors for one file and others for just loggings, you could:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
case $h in
2??|3??) type=valid ;;
4??|5??) type=error ;;
*) type=other ;;
esac
echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$type
done < logfile
.... or again some combination with other suggestions to build your output name.
I'm not sure I've understood the question, but these are a few options for what I think you are after.
If I've got it wrong, can you post some input and the expected out with the relevant file names you want to generate and I will have another go.
