Being a beginner in awk I need the following steps to be performed for text file
The text file contains

Increment 1

MAXIMUM 305.6

MINIMUM 31.62


N O D E O U T P U T




THE FOLLOWING TABLE IS PRINTED FOR NODES BELONGING TO NODE SET LOAD_NODE

NODE FOOT- U1 U2 U3 UR1 UR2
NOTE

59 -1.4877E-03 0.000 -0.3494 0.000 1.2497E-02
203 -7.3659E-03 0.000 -1.116 0.000 1.6711E-02


Increment 2 and some values etc..
Increment 3 and corresponding values...

I need the MAXIMUM (here 305.6) and U3 values (-0.3494 and -1.116) from the above text file.

I need to extract these 3 values from this text file for the final increment value i.e I do not need the values for Increment 1
instead need values for the final increment no in the text file. (If a text file has data for 34 increments I need the values only for 34th increment and not for others)

Murugs:

From what you've described in your data file: Both MINIMUM and MAXIMUM are field 1 and the corresponding value is field 2; Just read the file getting the last instance:

awk '
{
if($1 == "MAXIMUM&quot
maxval=$2
if($1 == "MINIMUM&quot
minval=$2
} END { print minval; print maxval } ' input.file

I understood the problem differently and here is my solution.

{
  if ($1 == "Increment") flg = 0
  else if ($1 == "NOTE") {
    flg = 1
    f4max = -999999
  }
  if (flg && NF>0 && $4 > f4max) f4max = $4
}
END { print f4max }

Hope this helps. CaKiwi

Thanks for the reply. I have posted one more question in the similar format and I have trouble in understanding you being a beginner. Pls respond to that so that I will better understand and pardon me for my ignorance.

Thanks
