 Posted: Sun Jan 02, 2005 2:57 pm Post subject: [Tool] Pulizia del portage overlay: cleanoverlay |
 |
|
Non avendo trovato niente di analogo in giro, ho scritto lo scrippettino cleanoverlay per pulire il tree del portage overlay. L'ho pensato per due funzioni:
- cancellare un ebuild non ufficiale quando questo viene inserito nel portage;
- mantenere aggiornata la propria versione modificata di un ebuild ufficiale.
Gli ebuild confrontati devono ovviamente avere la stessa versione. Ecco il codice:

Per usarlo la prima volta consiglio
Qualsiasi feedback è ben accetto

non avevo pacchetti "vecchi" da aggiornare in overlay, quindi non l'ho provato al massimo delle sue funzionalità...
solo 2 cosette:
- la dipendenza dall'utility "color" è proprio necessaria? 
- non so se l'opzione sia già presente in emerge... ma magari potresti integrare nello script un'opzioncina che lista tutti i pacchetti presenti in overlay (non solo quelli che si "sovrappongono" ad altri)... a volte capita che ne dimentichi alcuni in giro, per riscoprirli dopo mesi 
grazie cmq!

Ho utilizzato l'utility color per non dover inserire a mano i codici escape dei colori (è comunque possibile eliminarla) dato che è piccola e si compila subito. Per quanto riguarda l'opzione di listare i pacchetti posso inserirla senza problemi!  Appena ho un pò di tempo aggiorno lo script.
// EDIT: aggiornato lo script con l'opzione -l
Grazie per aver provato lo script, pensavo di aver creato qualcosa di inutile |
