What are other touch options?

The touch command has several options that can modify its behavior. Here are some commonly used options:

-a: Update the access time only, without changing the modification time.
```
touch -a filename.txt
```
-m: Update the modification time only, without changing the access time.
```
touch -m filename.txt
```
-c: Do not create a new file if it does not exist. This option prevents touch from creating an empty file.
```
touch -c filename.txt
```
-d: Set the date and time to a specific value instead of the current time. You can specify the date in various formats.
```
touch -d "2023-01-01 12:00:00" filename.txt
```

```

```
--help: Display help information about the touch command and its options.
