Bug Script to Match first field of two Files and print

I want to get script or command in Sun Unix which matches first fields of both the files and print the feilds of one files, example may make it more clear.




First field of first line is searched in second file as first field, and found so both lines(FIles A and File B) are printed in output.

Thanks in advance.

Something like:

awk -F, 'NR == FNR { A[$1] = $0; next } A[$1] { print $0 FS A[$1] } ' file2 file1

sort -d -t, +0 -1 InputFile1 >> InputFile1_sort
sort -d -t, +0 -1 InputFile2 >> InputFile2_sort

join -1 1 -2 1 -t, -o 1.1 1.2 1.3 2.1 2.2 InputFile1_sort InputFile2_sort >> OutputFile

join -t',' -j 1 <(sort infile1) <(sort infile2)


The result is with only a single name column, plus it's sorted but you might prefer it that way.
