Top Forums Programming awk to count occurrence of strings and loop for multiple columns Post 302919014 by Don Cragun on Friday 26th of September 2014 04:30:39 PM

What OS are you using? (Show output from uname -a.)

What is the value of LINE_MAX on your system? (Show output from getconf LINE_MAX.)

The obvious way to do things like this is with awk, but the standards only define the behavior of awk on text files. On many systems, a text file cannot have any lines longer than 2048 bytes and if you have 1100 fields in your input files, you have crossed that threshold.

How many lines are in your input file? What is the total size of your input file?

The header for your desired output file:
Code:
col2 count col1 col2 count col1 col3 count col1 ...col100 count col1

shows the 1st three output fields being duplicated but if I understand what you're trying to do, shouldn't the header be?:
Code:
col2 count col1 col3 count col1 ...col100 count col1

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
