Special Forums Windows & DOS: Issues & Discussions Gawk on Windows: Joining lines only if 1st field matches Post 302626847 by neutronscott on Thursday 19th of April 2012 10:11:45 PM

He used the files in reverse order. You mean, match case insensitive, but print case from file2...?

Code:
gawk -F":" "NR==FNR{a[tolower($1)]++;next}tolower($1) in a" 11.txt 22.txt

edit: i believe gawk even compiled on windows will not treat DOS line endings well. Try this next to remove them first
Code:
gawk -F":" "1{sub(/\r$/,"")}NR==FNR{a[tolower($1)]++;next}tolower($1) in a" 11.txt 22.txt

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
