How to copy directories recursively?

To copy directories recursively in Linux, you can use the cp command with the -r (or --recursive) option. This allows you to copy an entire directory along with all its contents, including subdirectories and files.

Syntax

cp -r source_directory destination_directory

Example

Copying a Directory: Suppose you have a directory named my_folder that you want to copy to a new location called backup_folder.
```
cp -r my_folder backup_folder
```
This command will create a copy of my_folder and all its contents inside backup_folder.
Copying to a Different Path: You can also specify an absolute path for the destination. For example, to copy my_folder to /home/user/backup/:
```
cp -r my_folder /home/user/backup/
```
Using Wildcards: If you want to copy multiple directories that match a pattern, you can use wildcards. For example, to copy all directories that start with project_:
```
cp -r project_* /home/user/backup/
```

Important Options

-v (verbose): Use this option to see the files being copied.
```
cp -rv my_folder backup_folder
```
-i (interactive): This option prompts you before overwriting files in the destination.
```
cp -ri my_folder backup_folder
```

Summary

Using the cp -r command is a straightforward way to copy directories and their contents recursively in Linux. This command is essential for tasks like backing up data or organizing files into different directories.
