Linux bin目錄是什麼
Linux bin目錄下都是二進位可執行文件,bin目錄放置的是最基本的一些命令的可執行文件,例如cp、mv、mkdir、chmod、chown等等,/usr下面也有一個bin目錄,它裡面的檔案也是一些指令的可執行檔。
二進位檔案
#簡單來說,文字檔案是基於字元編碼的文件,常見的編碼有ASCII編碼,UNICODE編碼等等。二進位檔案是基於值編碼的文件,你可以根據具體應用,指定某個值是什麼意思(這樣一個過程,可以看作是自訂編碼)。從上面可以看出文字檔基本上是定長編碼的,基於字元嘛,每個字元在具體編碼中是固定的,ASCII碼是8個位元的編碼,UNICODE一般佔16個位元。而二進位檔案可看成是變長編碼的,因為是值編碼嘛,多少個位元代表一個值,完全由你決定。
