Top Forums Shell Programming and Scripting Need help with awk to get values from input (newbie here) Post 302575479 by agama on Monday 21st of November 2011 11:04:39 PM

You are right to mark out identifying elements; the information I was looking for was there. Try running the command using nawk rather than awk:

Code:
nawk '
{ 
   gsub( ";", "", $0 );       # this might not be needed
   for( i=2; i <= NF; i += 2 ) 
       printf( "%d ", $(i)+0 ); 
   printf( "\n" ); 
 }'  input-file

For reasons unknown to me, awk on Solaris machines is very old and doesn't support many/any of the features found in modern versions of the tool. The installation of nawk seems to do better.

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
