I do not know book. I have done some C and awk is easy after referencing manual at The AWK Manual - Table of Contents

Is ok you don't have sample but knowing they are both csv just with different column we can use like:

Code:
awk -F',' 'NR == FNR { a[$5]++ } NR != FNR && a[$3]' file1 file2

NR is record number, by default a record is a line. FNR is file record number, thus, for the first file the two are the same. When file2 is opened, NR keeps incrementing, but FNR resets. So they are equal for file1 and we put the 5th field into associative array. So a[workorder#] is counting them... Then the expression is a[$3] for file2, to see if that key exists from file1 and the default action is to print the line...

So hopefully you only need to change the 5 and 3 for this to work.

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
