Top Forums UNIX for Beginners Questions & Answers Issue with awk when joining two files when field has '-' hyphen Post 303030106 by nezabudka on Wednesday 6th of February 2019 04:55:17 AM

Code:
awk -F, 'NR==FNR {T[$1]=$2;B[$1]=$2; next} ($1 in T) { $0 = $0 FS $1 FS T[$1] ;delete B[$1]} END { for(i in B) print i FS B[i] } 1' file1 file2

And I also made a mistake in the name of the array at the output. Fixed T on B

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
