Linux bin目录是什么
Linux bin目录下都是二进制可执行文件，bin目录放置的是最基本的一些命令的可执行文件，比如cp、mv、mkdir、chmod、chown等等，/usr下面也有一个bin目录，它里面的文件也是一些命令的可执行文件。
二进制文件
简单来说，文本文件是基于字符编码的文件，常见的编码有ASCII编码，UNICODE编码等等。二进制文件是基于值编码的文件，你可以根据具体应用，指定某个值是什么意思（这样一个过程，可以看作是自定义编码）。从上面可以看出文本文件基本上是定长编码的，基于字符嘛，每个字符在具体编码中是固定的，ASCII码是8个比特的编码，UNICODE一般占16个比特。而二进制文件可看成是变长编码的，因为是值编码嘛，多少个比特代表一个值，完全由你决定。
