 awk 'NR==FNR{a[tolower($1FS$2)]=$0;next}a[tolower($1FS$2)]{print a[tolower($1FS$2)],"->",$0}' file1 file2

The input files were originally Excel files which were saved as tab delimited text files.

I think that may be the source of the problem.

Hi danmero,
Thanks for your latest code - it works fine.

I have been playing round with it to give the output in double quotes with a semicolon but to no avail.

awk 'NR==FNR{a[tolower($1FS$2)]=$0;next}a[tolower($1FS$2)]{print a[tolower($1FS$2)],"->",$0";"}' file1 file2

For example I want the output to be like this:
"Cohen	Hannah	99 Moreton St" -> "COHEN	Hannah	30 Julia St";

Instead of this:
Cohen	Hannah	99 Moreton St -> COHEN	Hannah	30 Julia St

I have got the semicolon but struggling with the double quotes?

I could once again do with your help.

After some research and trial an error, this seems to produce the required output:
awk 'NR==FNR{a[tolower($1FS$2)]=$0;next}a[tolower($1FS$2)]{print "\42", a[tolower($1FS$2)],"\42","->","\42",$0,"\42" ";"}' file1 file2
