Eu tenho a seguinte configuração de partição do disco rígido:

SSD de 256 GB

/ dev / sda1- FAT 32 - Montado em / boot / efi

/ dev / sda2 - Montado na raiz do sistema de arquivos

/ dev / sda3 - Montado em / usr

1 TB HDD

/ dev / sdb1 - Troca de Linux

/ dev / sdb2 - Montado em / var

/ dev / sdb3 - Montado em / home

/ dev / sdb4 - Sistema EFI (desmontado)

/ dev / sdb5 - Montado na raiz do sistema de arquivos da 2ª distro (desmontada)

As duas distros são Lubuntu e Elementary. Na divisão acima, Elementar é o desmontado. Alguém pode me dizer como compartilhar arquivos entre essas distros? Atualmente, não consigo abrir ou executar nenhum aplicativo instalado no Elementary que seja do Lubuntu. Não consigo abrir várias pastas, por exemplo, / usr / local / bin

Fazendo isso manualmente

Monte a 2ª Distro com estes comandos

sudo mkdir /mnt/MyOtherDistro
sudo mount -t auto -v /dev/sdb5 /mnt/MyOtherDistro

Agora você poderá usar o Nautilus ou qualquer outro gerenciador de arquivos para navegar até o diretório /mnt/MyOtherDistro para visualizar / copiar / excluir arquivos, etc.

Você também pode mudar para um diretório na 2ª Distro:

cd /mnt/MyOtherDistro/home/Me/Documents

Quando terminar, desmonte a partição e exclua o diretório:

sudo umount -l /mnt/MyOtherDistro
sudo rm -d /mnt/MyOtherDistro

Fazendo isso com um script bash

Por sorte, eu estava trabalhando em dois scripts hoje à noite para montar e desmontar partições através de uma caixa de rolagem de linha de comando.

Montar uma partição

Para montar uma partição, execute o script bash sudo mount-menu.sh :

Desmontar uma partição

Para desmontar a configuração da partição por mount-menu.sh , execute o comando sudo umount-menu.sh . A mesma tela mostrada acima aparece, exceto que a partição já está montada e você a seleciona para desmontá-la. Primeiro você precisa criar o script /usr/local/bin/umount-menu.sh e copiar nas linhas abaixo:

#!/bin/bash

# NAME: umount-menu.sh
# PATH: /usr/local/bin
# DESC: Select mounted partition for unmounting

Torne-os executáveis

Depois de criar os arquivos, ambos os scripts devem ser marcados como executáveis:

sudo chmod a+x /usr/local/bin/mount-menu.sh
sudo chmod a+x /usr/local/bin/umount-menu.sh
