When making a symbolic link, check the command twice before you run it because several things can go wrong. For example, if you reverse the order of the arguments (ln -s linkname target), you’re in for some fun if linkname is a directory that already exists. If this is the case (a...

To create a symbolic link from target to linkname, use ln -s: 要从目标到链接名创建符号链接,请使用ln -s命令: $ ln -s target linkname The linkname argument is the name of the symbolic link, the target argument is the path of the file or directory that the link points to, and the -...

Shell 是一个程序,提供一个与用户对话的环境。这个环境只有一个命令提示符,让用户从键盘输入命令,所以又称为命令行环境( command line interface ,简写为 CLI )。Shell 接收到用户输入的命令,将命令送入操作系统执行,并将结果返回给用户。 Shell 是一个命令解释器,解释用户输入的命令。它支持变量、条件判断、循环操...
1、hard link(硬链接实际链接):只是在某个目录下新建一条文件名链接到某inode号码的关联记录而已。 2、symbolic link(符号链接,快捷方式):再创建一个独立的文件,而这个文件会让数据的读取指向它链接的那个文件夹的文件名。 3、将/etc/passwd复制到/tmp下面,并且查看inode与block ...
