Ok, that seems do it. I have for the most part never used or
needed the *xxxxx notation, so though I have been using Perl for years,
not sure of all that it implies.
So here is what I did:
if ( $GlblInfo{audit} ) {
print "All STDOUT/STDERR will be assigned to this scripts audittrail
log!!\n"x3;
open(OLD_STDERR,">&STDERR") or die "Failed to save STDERR"; #pulled
this from the internet
}
If I do not do this before the print, then I get print on a
closed filehandle.
local *STDOUT;
Then I placed the code to capture the STDOUT/ERR to a file. This worked
as expected and placed all that was being displayed to the screen to
disk.
I then had the following:
if ( $GlblInfo{audit} ) {
print "\n\n*****Should be last line in the audittrail
file...*****\n\n";
open(STDERR,">&OLD_STDERR") or die "Failed to restore STDERR";
select(STDERR);
open(STDOUT , '>-') || die "Unable to open STDOUT: $!";
select(STDOUT);
if ( $GlblInfo{continues} ) {
print "\n\n" . "*EndOfProg*"x7 . "\n\n";
}else {
print "\n\n" . "**Error*"x9 . "\n\n";
}
}
Now everything seems to be working as I would have expected. I
added an error to the open on STDOUT and it threw up the error to
STDERR.
As to the printf verses print, sorry, but I am the only one
doing the work here using Perl. There may be overhead and I will try to
change the thought processes.
I do appreciate the list and it's help..
Thanks again.
If you have any questions and/or problems, please let me know.
Thanks.
Wags ;)
