Shell Programming and Scripting

Hi,
I have an awk code that reads an input file, checks the 4th column and tells if its fine.

Code:

#!/bin/ksh
{ if ($4 == 0)
print "fine"
else
print "some problem" }' FILENAME

My problem is that, I dont want to check the first 3 and last 3 lines.
This can be hard coded by using BEGIN and END in awk code.
But, I dont want to hardcode.
Could you please suggest, if I can go with FOR loop or something. if yes,how?

Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

Code:

awk 'NR > 3 && nr - 3 > NR {
  print $4 == 0 ? "fine" : "some problem"
  }' nr="$(wc -l < infile)" infile

TIMTOWTDI:

Code:

head -n -3 inputfile | tail -n +3 | awk '....'

Not sure what is the syntax error over here.
its saying

Code:

 syntax error The source line is 2.
 The error context is
                 >>> while <<<  (NR > 3) {
 awk: Quitting
 The source line is 2.

my code is

Code:

FILE=$1
awk '
while (NR > 3) {
 if ($4 == 0)
 print "fine"
 else
 print "some problem" } ' $FILE

tried a number of times..with multiple trail n error. But in vein. PLz help

Just read and follow the suggestions you received ...

Hi Radoulov,
thanks for responding.
Thing is that, The piece of codfe that you have provided produced syntax error,even though I could understand the logic behind your code.
After that, I tried to resolve it in many ways and tried with a while condition.
m posting my query again because, I could not get exactly from the error message, where i am going wrong.
else no one wud play and pass one's time with silly ping pongs.

OK,
just copy/paste here the command you execute and the exact error message
(I mean the code from the previous posts, not the one you modified)
so we don't have to guess.

In any case the standard suggestion applies: use nawk or /usr/xpg4/bin/awk if you're on Solaris.
