使用AWK处理文件时出错

我有一个文件遵循以下模式：

@ERR202858.267 267 length=100
CGGCCATGCGCGCGGTAGCATATGCATCCTTGCCCTGTTGTTA
+ERR202858.267 267 length=100

+ERR202858.268 268 length=100
FFEFEFFFFB@>=D9B>7AB>C4C>@C@?BD??6A=;+,@B@3@@>

变量$header应为@ERR202858

但是，我在一个文件中获得了此错误：

为什么会这样？用于在其他文件中工作的脚本…

您需要为printf指定一个格式字符串

与printf%s类似，\n$0
