Linux / Unix: Command Show Directory Listing

To show the directory listing in a Unix or Linux shell, you can use the ls command.

The ls command lists the files and directories in a directory, displaying the names and other information about each file and directory.

By default, the ls command lists the files and directories in the current working directory. To list the files and directories in a different directory, you can specify the directory path as an argument.

For example, to list the files and directories in the /etc directory, you can use the following command:

ls /etc

This will display a list of the files and directories in the /etc directory.

The ls command has many options that allow you to customize the output, such as the -l option to display a long listing with additional information about each file and directory, or the -a option to show hidden files.

For example, to show a long listing of the files and directories in the /etc directory, including hidden files, you can use the following command:

ls -la /etc

This will display a long listing of the files and directories in the /etc directory, including hidden files, which are typically denoted by a . character at the beginning of the name.

For more information about the ls command and its options, you can consult the documentation for your specific Unix or Linux system.
