Join files based on column

Hi,

Thanks!! I found an alternate solution.

Code:
 
awk 'FNR==NR{a[$1]++;next}a[$1]' FileA FileB | awk -F '\t' 'BEGIN {OFS=FS} {print $0,"FIleA&FileB"}' > one.txt
 
awk 'FNR==NR{a[$1]++;next}!a[$1]' FileA FileB | awk -F '\t' 'BEGIN {OFS=FS} {print $0,"FileB"}' > two.txt
 
awk 'FNR==NR{a[$1]++;next}!a[$1]' FileB FileA | awk -F '\t' 'BEGIN {OFS=FS} {print $0,"FileA"}' > three.txt
 
cat one.txt two.txt three.txt > FileC.txt

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION

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
