Java ile Uzak Masaüstü Komut Satırında İşlemler

Bazı durumlarda bir batch program ile server'a bağlanıp belli komutlar çalıştırmamız gerekebilir. Kopyalama, backup alma vb işlemleri otomatize etmenizde faydalı olacaktır.

Aşağıdaki ekran çıktısında linux server'a bağlanıp örnek olarak 'ls' komutunu çalıştırdım. Uygulamayı jar olarakta projenize dahil edebilirsiniz. İşletim sistemi bağımsız olarak kullanabilirsiniz.
