Hi Sander,

Welcome to the forum.. In future it is best to create a new thread and then refer to this thread for example..
Your case is a little bit simpler, except for the fact that your input files use different field separators.
You could give this a try:
Code:
awk 'NR==FNR{A[$1]=$2;next}A[$1]{$2=A[$1] FS $2;print}' file2 FS=, OFS=, file1

Which will print only those records that have a match in file2 and it will use the value in the second field from that file...

zdiff

ZDIFF(1)                                                      General Commands Manual                                                     ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only file1 is specified, it is compared to the uncompressed contents of file1.gz.  If two files are specified, their  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.

                                                                                                                                          ZDIFF(1)
