Top Forums UNIX for Dummies Questions & Answers Is it possible to extract rows with the same first column and then calculate its percentage? Post 302432862 by pxalpine on Sunday 27th of June 2010 05:30:02 PM

Hi vgersh99,

Thanks for your help. I tried your code, and got this in return:

awk: weird printf conversion %
awk: not enough args in printf( [%s]=%.2f%)

Do you know what the problem may be? And I'm jw, but can you explain what the line of code printf("\t[%s]=%.2f%\n" does?

Thanks, I'm starting to see just how powerful UNIX scripting is.

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
