I am new with awk scripting. I am trying to do the following:

1.) Parse various files with multiple extensions (.csv, .txt, .nbe)
2.) Print a field=>Sort via Uniq
3.) I am trying print a line that shows the total
4.) Output to a console and text file

* Will I be able to read via 'cat' a group of files in a directory.

awk
BEGIN {

if ( $0 ~ /|/) {
FS=":"; }{
print "Tool #1 Scan Results"
print --------------------
print $2 | Sort | uniq
print "Total IP Count: $count" # Not sure how to come up with the $count of IPs
}
else ($0 ~ /Interesting/) {
print "Tool #2 Scan Results"
print ------------------
print $4 | Sort | uniq
print " Total IP Count: $count" # Not sure how to come up with the $count of IPs
}
}
