Linux bin目錄是什么
Linux bin目錄下都是二進(jìn)制可執(zhí)行文件，bin目錄放置的是最基本的一些命令的可執(zhí)行文件，比如cp、mv、mkdir、chmod、chown等等，/usr下面也有一個(gè)bin目錄，它里面的文件也是一些命令的可執(zhí)行文件。
二進(jìn)制文件
簡(jiǎn)單來(lái)說(shuō)，文本文件是基于字符編碼的文件，常見(jiàn)的編碼有ASCII編碼，UNICODE編碼等等。二進(jìn)制文件是基于值編碼的文件，你可以根據(jù)具體應(yīng)用，指定某個(gè)值是什么意思（這樣一個(gè)過(guò)程，可以看作是自定義編碼）。從上面可以看出文本文件基本上是定長(zhǎng)編碼的，基于字符嘛，每個(gè)字符在具體編碼中是固定的，ASCII碼是8個(gè)比特的編碼，UNICODE一般占16個(gè)比特。而二進(jìn)制文件可看成是變長(zhǎng)編碼的，因?yàn)槭侵稻幋a嘛，多少個(gè)比特代表一個(gè)值，完全由你決定。
