Operating Systems AIX Issues with AWK Post 302313727 by alanp on Wednesday 6th of May 2009 10:35:17 AM

I have written a script that combines several files that contains both similar and dissimilar fields within each record. The resultant file needs to be a concatenation of all files vertically, not horizontally (ie can't use cat). Can't use join as any common field can only be displayed once in the resultant file.
So I created a variable "$rec1_field" that contains the order of the variables I need to be output for each record, as parsed by awk.
The variable literally contains "$1,$2,$3,....". What I thought I could do ,is replace {print $1} within awk with {print $rec1_field}, and let awk expand the variable to $1,$2,etc.

I developed the script on a Linus Red Hat platform and it works 100%, but when I run it under AIX it fails. See previous posts.

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
