Shell Programming and Scripting

hi
i am writing a korn shell script to compile all programs there are arount 2000+ files now i have a script that can compile programs but i want to show status of compilation because to compile all programs it takes around 10-15 mins so how can i display status like it should print no of files compiled aftere evey 20 files

like

$20 files compiled
$40 files compiled

my shell script is simple

Code:

cat filename | while read i
do
compile $i 
done

Code:

#!/bin/ksh
while read i
do
   cnt=$((cnt + 1))
   (( $(( cnt % 20 )) == 0 )) && echo "${cnt} files compiled..."

   compile $i 
done < filname

#!/bin/sh
cnt=0
while read i
do
cnt=$((cnt + 1))
compile $i
done < filname
echo "$cnt files compiled..."

does this not work? I use .sh though!

correct me?
