Script em bash para compilação automática do kernel Linux-libre 4.4.6 no Ubuntu/Debian/Mint/Trisquel 32/64 bits para PC/notebooks que tenham no mínimo 2 GB de memória RAM. Ele baixa e compila tudo automaticamente usando "CFLAGS -MARCH=NATIVE +  Ofast", só sendo necessário escolher a arquitetura exata do seu processador no menuconfig.

Como executar no terminal:

$ time sudo bash scriptkernel-libre-4.4.6.sh

#Script para automatizar a mudança das flags na hora de compilar o kernel.
#Mais informações sobre como compilar o kernel para seu processador:
#http://ubuntuforum-br.org/index.php/topic,81718.0.html

#Modo de usar:
#Após baixar o kernel, descompactar, criar um link simbólico para ele no /usr/src/linux:
# cd /usr/src/linux   
# sudo su
# chmod +x script.sh
# ./script.sh
#O script deve ser executado como root. Recomendo que use sudo su - e rode o script ao invés de sudo sh script.sh


#Script criado por André Steinn

#Aqui é a lista de arquivos que ele vai dar replace no -march= por -march=native. Você pode mudar essa lista de arquivos passando a lista pela opção a e separados pro virgula
#e.g.: ./script.sh -a arch/x86/boot/compressed/Makefile,arch/x86/boot/Makefile,arquivo1,arquivo2,arquivo3

arquivos=( "arch/x86/boot/compressed/Makefile" "arch/x86/boot/Makefile" "arch/x86/kernel/acpi/realmode/Makefile" "arch/x86/Kconfig.cpu" "arch/x86/Makefile" "arch/x86/Makefile_32.cpu")

#Aqui eu verifico se a pessoa passou algum argumento na hora de executar o script
while getopts ":a:c" opt; do
  case $opt in
    a)
      echo "Você setou uma lista de arquivos personalizada: $OPTARG" >&2
   IFS=',' read -ra arquivos <<< "$OPTARG"
      ;;
    \?)
      echo "Opção inválida: -$OPTARG" >&2
      exit 1
      ;;
  esac
done

#Aqui eu faço um loop e altero os arquivos, removendo o -march=() por -march=native
for i in "${arquivos[@]}"
do
   echo "Path no arquivo:"$i
   sed -e 's/-march=\([A-Z0-9a-z]\+\)/-march=native -Ofast /g'  $i > "$i.file_changed"
