How to use recursive ls in Linux

In Linux systems, the "ls" command is a very useful tool that provides a concise overview of the files and folders in the current directory. Through the "ls" command, you can quickly view important information such as permissions and attributes of files and folders. Although the "ls" command is a basic command, by combining different subcommands and options, it can become an important tool for system administrators and users. By skillfully using the "ls" command and its various options, you can manage your file system more efficiently, quickly locate the files you need, and perform various operations. Therefore, the "ls" command can not only help you understand the current directory structure, but also improve your work efficiency.

For example, in Linux systems, you can easily view the contents of a directory and its subdirectories by using the "ls" command with the recursive option. The recursive option allows you to drill down into subdirectories and view all files and folders within them, a feature many users may be unfamiliar with. Therefore, here is a brief introduction on how to use the recursive "ls" command in Linux.

How to use recursive "Ls" in Linux

To modify the "ls" command to display a recursive file list, the "R" option must be used with it.

LS-R

As shown in the previous image, it lists the contents of all available directories and subdirectories in the currently selected directory.

You can also use the "L" option in the syntax to view files, directories and their permission attributes recursively, as shown below:

ls—lR

Suppose you want to know the permissions of each directory in your home directory. It can be time consuming, but you can use the previous command instead.

In addition, the aforementioned method will display both files and directories in the results. If you just want to display directories, consider using the recursive "ls" command in conjunction with the "grep" command.

ls—R| grep ":$"

in conclusion

Listing the contents of a directory is a basic task for Linux users, and it is accomplished using the "ls" command. However, if you often want to view other files and subdirectories in a directory, you can use the recursive option. So, we explained the 'ls' and 'recursive' options with various examples which you can use in your system as well.
