Je ne vois pas tr=C3=A8s bien pourquoi utiliser basename ici (son r=C3=B4le=
 est en
g=C3=A9n=C3=A9ral de supprimer la partie r=C3=A9pertoire d'un chemin). Il s=
uffit de
faire une expansion en supprimant le suffixe.

for file in *_gif.gif ; do convert "$file" "${file%_gif.gif}.png" ; done

J'ai aussi chang=C3=A9 la liste du for : si tu as un fichier sans la partie
"_gif" tu r=C3=A9cup=C3=A9rerais xxx.gif.png
