I want to test if a file is a gif image or not.
Is it practicable using a module?

$mm->removeFileExts
Removes filename pattern checks. Specify one or more patterns. If no
pattern is specified, all are removed.

You can check whether a file purports to be a GIF file by
checking its first three bytes:
my $file = 'filename.gif';
my $type;
{
open my $fh, $file or die $!;
read $fh, $type, 3;

print "filename to check: ";
my $filename = ;
chomp $filename;
open IN, $filename or die "Could not open file to check specs: $!";
binmode IN;
my $gif_label;
read (IN, $gif_label, 6);
chomp $gif_label;
if ($gif_label =~ /^GIF8[79]a/) {
