Olá "linuxers", estou aqui para compartilhar com vocês um script (Shell) que criei para descarregar e instalar a SEMPRE a última versão do Eclipse estável, ou seja, o script tem a função de pegar o último codenome e a última release estável do Eclipse, por exemplo: Mars/R.

Resolvi criar esse script, porque o Eclipse é apenas extrair e usar no GNU/Linux, deixando sua "instalação" meio chocho (onde eu tirei essa palavra na minha mente?), sem um atalho em "/usr/share/applications", não cria link simbólico na pasta "bin", e ter aquele "trabalhinho" de ficar entrando no site do Eclipse, para baixar a última versão (caso não queira atualizar a versão que já possuí). Tudo bem, você pode fazer tudo isso manualmente, mas um script que faz isso com apenas uma linha de comando é bem melhor, seja qual for sua distribuição.

O script está armazenado no meu Gist do GitHub, e isso possibilita de utilizar uma única linha para fazer todo processo, através do cURL com opção "L".

Para fazer o download e instalação da última versão do Eclipse com uma única linha de comando, acesse o script no meu Gist (no final do texto) e na descrição do script, tem a forma de instalação utilizando o cURL e outros comentários.

Agora se quer realizar o download do script para rodar localmente, você pode, ele tem essa opção, irei disponibilizar aqui, mas logo aviso: "O SCRIPT PODE FICAR OBSOLETO AQUI", caso eu queira modificá-lo no Gist ou algum amigo dê dicas para modificá-lo, pois eu uso mais Gist.

Se você for baixar e usar o script localmente, você terá que alterar o parâmetro da função "_RUN_OPTION" para "local", assim você terá o menu de instalar (-install) e desinstalar (-uninstall) habilitado no script. Caso deixe como está, ao executar o script ele irá fazer o download e instalar automaticamente e não entrará no menu.

Nota: coloquei essa função "_RUN_OPTION" com opção de usar (ou não) menu do script, porque como o script está armazenado no Gist, o "curl -L" não aceita a utilização de menu. O script usa o "sudo" então seu usuário terá que estar no /etc/sudoers.
