What are common command-line arguments?

Here are some common command-line arguments that are widely used across various command-line utilities:

-h or --help: Displays help information about the command, including usage and available options.
```
command --help
```
-v or --version: Shows the version of the command or program.
```
command --version
```
-f: Often used to force an action, such as overwriting files without prompting.
```
rm -f filename.txt  # Force delete a file
```
-r or --recursive: Used to perform actions recursively, such as deleting directories and their contents.
```
rm -r directory_name  # Recursively delete a directory
```
-i: Prompts for confirmation before executing an action, often used with delete commands.
```
rm -i filename.txt  # Ask for confirmation before deleting
```
-n NUM: Specifies a number, such as the number of lines to display or process.
```
head -n 10 filename.txt  # Show the first 10 lines
```
-q or --quiet: Suppresses output messages, making the command run quietly.
```
command -q  # Run quietly without output
```
-o: Often used to specify an output file for commands that generate output.
```
command -o output.txt  # Redirect output to a file
```

These arguments can vary by command, so it's always a good idea to check the help documentation for specific commands to understand their options. If you have a particular command in mind, feel free to ask!
