AWK- processing data inside start/stop pairs but ignoring start/stop lines


Hi all

I would like to know how to perform a small task in AWK. I'm able to extract data from a text file using "awk '/start/,/stop/'" all fine - I now wish to process the data further from the extract using AWK but ignoring the start/stop pair used to define the data set.

.
Start of text
line1 word1 word2
line2 word1 word2
End of Text

Is this possible please - any ideas ? Using the start/stop pair thereby inclus the first and last lines in the output, which I don't wish to process.

Cheers - Ian

You can check whether the line matches the start or stop pattern. If so, do nothing. Else continue with whatever you need to do.

Code:
awk '/b/, /d/ {if ($0 ~ /b/ || $0 ~ /d/) {} else {print;}}'

Something like that maybe:
Code:
awk '
/Start of text/ {
  process="true"
  next
}
/End of text/ {
  process=""
  next
}
process=="true" {
  ...do what you have to do...
}'
