I have a shell script that calls 2 perl scripts.

A.ksh
---

A1.pl
A2.pl

==================

Now A2.pl calls 3 perl scripts within itself to generate the final result through the "system" command.

Is there any way that when I run

ksh A.ksh

when the program is executing, I can show the progress in the form of dots(....)

I think this is only possible if all of your scripts would echo one or more dots to the terminal (without linefeed, of course) at some stage in their processing.
Your calling script cannot do that on their behalf.

This should give you the framework you need.

You may need to change

/bin/echo -n .

to

echo -e ".\c"

or

echo ".\c"

if the dots don't appear on the same line.
#!/bin/ksh

function dots {
  trap 'return' 3

  while true
  do
    /bin/echo -n .
    sleep 1
  done
}

echo "start"
dots &
pid=$!
A.pl
B.pl
kill  $pid
echo finish

Open in new window

Hehe, Tintin,
that's a real "Windows-style" progress meter! Writing a dot every second, regardless of the actual progress ...
Just joking!
