Please become accustomed to deploy utmost care when specifying your request, esp. constraints like "Exactly (no more and no less than) the GUIDs in file1", and give people a chance to understand what be test.csv, and what *.csv.
Why, for example, not just simply
Code:
awk -F, '{TMP = $2; gsub (/^.*\/|\..*$/, _, TMP); print TMP, $2}' OFS=, file2

I guess because you want to discriminate file2 with the values in file1. How about
Code:
awk -F "[,]" 'NR==FNR{A[$1]; next} { for (a in A) {if ($2 ~ a) print a, $2}}' OFS=, file[12]

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
