Question Find, Replace & Edit a string?

Is this something SED would be used for or can AWK do it?

I have a string that I would like to chop bits out of and re-arrange some of the rest.

Basically I want to change this:
Code:
<log4j:event logger="webserver" timestamp="1240110840109" time="Sun Apr 19 04:14:00 BST 2009" level="INFO" thread="webserverThread-0:0" schema="LMS">
to this:
Code:
14:00,19-04-2009
Thanks.

I guess AWK should do it. If the fields are fixed then just print them.
Something like this

echo "<log4j:event.........schema="LMS">" | awk '{ print $3,$4, substr($5,3,5), $5...'}
Here $3, $4 prints te whole word/field and substr($5,3,5) prints 5 characters of 5th field starting from the 3rd letter.

Modify the awk with your requirements.

Thanks and Regards,
Gideon.

Thanks for that!

Not sure how I can go about changing the Apr into a 4 and Jan into a 1 and so on...

Any ideas?

I don't know if it's the best way, but I'd setup a script with a line like:
monthnum=0
for month in (Jan Feb Mar Apr); do
monthnum=$(($monthnum+1))
sed -e "s/'$month'/'$monthnum/" <infile >outfile
done

Thats off the top of my head, obviously you'll need to write the whole script
