La commande file permet d'afficher le type mime d'un fichier. Les résultats de cette commande peuvent varier en fonction du fichier magic (/usr/share/file/magic sur debian et ubuntu) de votre distribution linux.
Petit exemple :
root@home:~# file -i /tmp/sample-file/mp3.mp3
/tmp/sample-file/mp3.mp3: audio/mpeg
Et le bonus du chef pour connaitre les types mimes des fichiers d'un répertoire :
root@home:~# find /tmp/sample-file/ -type f -exec file -i {} \;
