How can the shell display all files in a directory?
In the shell, you can use the ls command to list all the files in a directory. The specific command format is:
ls [选项] [目录]
In the options section, you can choose to add some parameters optionally, such as -l to list files in detailed form, -a to show all files (including hidden files starting with .), and so on.
The catalog section indicates the directory path that will be listed for the files. If no directory is specified, it defaults to the current directory.
For example, to list all the files in the current directory, you can simply run the following command:
ls
To list all files in a specific directory, you can pass the directory path as an argument to the ls command, for example:
ls /path/to/directory
This will list all the files in the directory at /path/to/directory.
