slackpkg update gpg && slackpkg update


kernel-generic
kernel-headers
kernel-huge
kernel-modules
kernel-source

A ideia seria filtra a saída do "slackpkg update" para os pacotes do kernel e joga no notify-send, mostrando somente os pacotes do kernel.

Ex:

notify-send --icon=dialog-information -t 10000 "Existe atualização para o seu kernel....

$pacotes
"

Olha se esse script te ajuda:

#!/bin/sh
#
# Script para verificar se existe novas atualizaçoes do kernel no "Slackware64-current".
# Por Patrick Ernandes, suporte@ernandes.info

FILE="/tmp/ChangeLog.txt"

Obrigado em responde ao tópico.

Nem todo mundo usa o current . Temos de identifica essa variante ai.

O problema principal seria no kernel-huge e kernel-generic, quando atualiza gerando o famoso "Kernel Panic" , após reboot no generic . Acho que os outros pacotes do kernel não tem problema quando atualiza.


Por que usou essa parte para identifica os números dos arquivos na pasta:

ls -1 /var/lib/pkgtools/packages/kernel* | wc -l

$ ls /var/lib/pkgtools/packages/
ls: não é possível acessar '/var/lib/pkgtools/packages/': Arquivo ou diretório não encontrado


Na parte de verifica a versão do site com a versão instalada do kernel não bateu

site => 4.4.14
instalada => 4.4.276

Bom, isso está funcionando muito bem no current.
Eu prefiro monitorar todos os pacotes referente ao kernel.
Mas você pode ajustar para versão do seu slack e modificar os pacotes que queira monitorar.
