Below is my code. It runs a backup program from a pTk GUI.
My problem is at the 'system($cmd)' statement. The command gets
executed before the message gets displayed in the text widget.
I want a message that tells * is being done, then when the process is
done a message that says * is done along with relevant error codes.
Is there a better way to do this? And why are the messages displayed
at the wrong time?
my @cmd = "";
push (@cmd , $prog_args , $fullf
+ile2 , "/" );
my $cmd2 = join " " , @cmd
+;
$text -> delete ('1.0' , 'end' );
$text -> insert ('end' , "\n" );
$text -> insert ('end' , "THIS
+OPERATION SHOULD TAKE 5 min. to 15 min. \n ", 'highlite' );
my $exit_status = system(
+$cmd2 );
print "\$exit_statu
+s at L1447 =: $exit_status\n";
if ( 0 == $exit_sta
+tus )
{
$text -> insert ('end' , "\n\n" );
$text -> insert ('end' , "DONE! \n", 'h
+ighlite' );
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
