You can experiment with File::Type, File::LibMagic, File::MMagic, etc.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    These only provide the MIME type: 

    perl -MFile::MMagic -E 'say File::MMagic->new->checktype_filename(pop)
+' /usr/lib/x86_64-linux-gnu/libHalf.so.12.0.0
application/octet-stream
perl -MFile::Type -E 'say File::Type->new->checktype_filename(pop)' /u
+sr/lib/x86_64-linux-gnu/libHalf.so.12.0.0
application/x-executable-file

    update

    File::LibMagic is more informative: 
    perl -MFile::LibMagic -E 'say File::LibMagic->new->info_from_filename(
+pop)->{description}' /usr/lib/x86_64-linux-gnu/libHalf.so.12.0.0
