如何使用 printf 在打印命令中添加新行？
printf "I want this on a new line!"
I thought it would be something like this but it didn't work
我以为它会是这样的，但它没有用
printf "/n I want this on a new line!/n"
Thanks in advance for the help!
在此先感谢您的帮助！

To write a newline use \nnot /nthe latter is just a slash and a n
要编写换行符，请\n不要/n使用后者只是一个斜杠和一个

Try this:
尝试这个：
printf '\n%s\n' 'I want this on a new line!'
That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.
这允许您将格式与实际文本分开。您可以使用多个占位符和多个参数。
quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f %s\n' "$quantity" "$price" "$description"
38 142.15 advanced widget
