Script per Installare l'ultima versione di Firefox su Slackware
« il: Domenica 19 Marzo 2017, 08:27:58 »
Con Slackware (stable) si ha installata la versione ESR di Firefox. La Versione esr si aggiorna solo con le patch di sicurezza, senza avanzare di versione, fino al rilascio della ESR successiva.

Se si vuole avere la più moderna e aggiornata versione di Firefox disponibile é sufficiente eseguire lo script che sto per riportare...

Apri un editor di testo (leafpad, mousepad, nano, eccetera), crea un nuovo documento vuoto e incollaci dentro quest testo:

Codice: [Seleziona]
#!/bin/bash
# latest-firefox Version 1.3.9

# This script will find the latest Firefox binary package, download it
# and repackage it into Slackware format.

# I don't use Firefox for regular browsing but it is handy for
# comparative tests against Vivaldi. :P

Salva il documento con questo nome:

latest-Firefox.sh


Adesso apri un terminale, portati nella directory che contiene lo script appena creato, sali con i privilegi (su) e lancia l'esecuzione con:

Codice: [Seleziona]
sh latest-Firefox.sh
Terminata la compilazione del pacchetto (pochissimi minuti) troverai il .txz nella directory /tmp (vedi l'output...), Installalo con il solito comando:

Codice: [Seleziona]
upgradepkg --install-new
Conserva lo script e riutilizzalo per ottenere sempre la versione più aggiornata di Firefox.

Nota: mi piacerebbe citare l'autore e la fonte dello script, ma non me lo ricordo...  :)
