What does IO::File=GLOB mean?

[ITadvice]

I put some information in a temp file but when I try to print what’s in the file, I get this instead--> IO::File=GLOB(0x8791…). What does this mean? Is the data not being written into the temp file? Here is a portion of my code.


foreach $line (@data) {
chomp $line;

($timestamp, $dump1, $dump2, $out, $dump3, $dump4, $dump5, $in, $dump6)=split(/\t/, $line); # Sort out needed columns

foreach ($line) { # Format time/date
my $datetime = DateTime::Format::Excel->parse_datetime($timestamp);
$timestamp = $datetime->ymd . $datetime->hms;
seek ($fh, 0, 0) or die "Seek: $!";
print $fh "$timestamp $out $in\t";
}
print $fh;
}
close (FILE);

your not printing what is in the file.. you are printing the filehandle itself

Further up in my code I have the following line:

my $fh = IO::File->new_tmpfile or die "Unable to make new temp file: $!";

Does this put the contents of the file in $fh or is it just pointing to the file? Because this is a randomly generated file, I want to be able to access the file using a variable since I don't know the name of the temp file.

The code above creates the filehandle $fh, $fh is a pointer to the file, it is not the file itself. Are you sure you want to use the new_tmeplfile method?

new_tmpfile

Creates an IO::File opened for read/write on a newly created temporary file. On systems where this is possible, the temporary file is anonymous (i.e. it is unlinked after creation, but held open). If the temporary file cannot be created or opened, the IO::File object is destroyed. Otherwise, it is returned to the caller.
