Top Forums Shell Programming and Scripting Using awk command for .csv file Post 302376658 by rdcwayx on Wednesday 2nd of December 2009 03:40:41 AM

first in your sample file, only 45 column, if split by ;

Code:
$ awk -F\; '{print NF}' input
45
45
45

If you need output selected columns, you can use below ways:

Code:
awk -F\; '{print $3,$10,$30}' input
cut -d\; -f3,10,20-30,42- <input

Still I don't get how you get this output from your input file, can you explain on it?

Code:
array_16 = column16
last_value = column_16_lastrecord

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
