Il comando che dovrete implementare come script shell o programma python e' statlen.&lt;br /&gt;
Data una directory statlen fa una statistica sulla lunghezza dei nomi dei file presenti in tutto il sottoalbero con radice nella&lt;br /&gt;
directory passata come parametro.&lt;br /&gt;
es.&lt;br /&gt;
$ statlen /tmp&lt;br /&gt;
2: 2&lt;br /&gt;
3: 10&lt;br /&gt;
5: 4&lt;br /&gt;
...&lt;br /&gt;
significa che in tmp (e in tutte le sottodir.ectory di /tmp) ci sono 2 file con nome di due caratteri, 10 con nomi di 3 caratteri e&lt;br /&gt;
cosi' via.&lt;br /&gt;
&amp;lt;/source&amp;gt;&lt;br /&gt;
