Et voila - there you are:
Quote:
Code:
grep -i 'AADESH,id2_1_*,AELA' COMBO_JUNK

It is looking for strings with 0 to n occurrences of _, not \*, which was what you intended. So - it's not an escape too many, but one too few.

btw - when mentioning "meaningful lines" I was talking of those around the occurrence of the problem.
btw2 - indenting and pretty printing like you do in your awk program usually is good practice, but in this simple case a one liner might be easier to read and handle: awk -F, '{C4+=$4} END {print C4}' will do!

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
