不，它們或多或少是同樣優(yōu)秀的，各有各的特點。只不過 Linux 在泛用性方面更加優(yōu)秀，比如可以運行在從超級計算機到Raspberry Pi 的任何設(shè)備上。你可以得到源代碼，有一個充滿熱情的用戶和維護者社區(qū)，而且它是免費提供的。
如果你想要商業(yè)支持，也可以從 Red Hat、Canonical 和 Oracle 獲得。而這也是 Linux 能夠從一些企業(yè)中取代 Unix 的關(guān)鍵之處，因為很多公司不相信 ”免費“，他們更樂意為支持付費。Linux 的崛起并不都是以 Linux 免費為前提的。商業(yè) Linux 幫助擊敗了商業(yè) Unix。
Linux 比 Unix 更成功嗎？好吧，這也取決于對給成功的定義。如果擁有比其他操作系統(tǒng)更多樣化和更廣泛的使用是一個衡量標準，那么是的。如果是運行該操作系統(tǒng)的設(shè)備數(shù)量最多，那么是的。
紅帽公司以 340 億美元的價格出售，可能也是Linux 在商業(yè)成功方面上的一次成功。
Linux 殺死了 Unix 嗎？
更準確地說，是 Linux 讓 Unix 停住了腳步，然后邁入了 Unix 的賽道。
Unix 仍在那里，運行著關(guān)鍵任務(wù)系統(tǒng)，這些系統(tǒng)功能正常，運行穩(wěn)定。這種情況會一直持續(xù)下去，直到對應(yīng)用程序、操作系統(tǒng)或硬件平臺的支持停止。
但是對于新的安裝來說呢？有足夠多的 Linux 變體，使得選擇商用 Unix 的理由非常非常困難。
