How to change the date format?

You can change the date format in the date command by using format specifiers. Here’s how to do it:

Use the date command followed by the + sign and your desired format in quotes.

Here are some examples of custom date formats:

Standard format (YYYY-MM-DD HH:MM:SS):
```
date "+%Y-%m-%d %H:%M:%S"
```
12-hour clock format:
```
date "+%I:%M:%S %p"
```
Including the day of the week:
```
date "+%A, %B %d, %Y"
```
Compact date format:
```
date "+%y%m%d"
```

You can experiment with these formats by typing them in your terminal. The + sign indicates that you are specifying a custom format. For a full list of formatting options, you can refer to the manual page by typing man date in the terminal.
