文件内容是这样的 但是可能没有这样整齐 可能是一条龙的写下来 中间只有空格
我的需求是 用一个变量能代替这里面的段落 段落是已 metatag为分割的，既两个metatag之间算一段 （算上metatag）


那位大哥大神能帮下 谢谢

用一个变量能代替这里面的段落

这句话什么意思，你那么多段落，怎么用变量代替？

    try:

1. awk -vRS='<metatag' -vORS="\n" 'NR>1{print RS$0}'

micmouse521

太感谢了 能请问下  vrs 这三个参数都代表什么吗？

yinyuemi

回复 6# micmouse521

RS：记录分隔符(默认是一个换行符)。
ORS：输出记录分隔符(默认值是一个换行符)。

    "awk -vRS" === "awk -v RS"
    "awk -vORS" === "awk -v ORS"


给RS ORS这两个变量重新赋值

收到 谢谢哈  看来还得抽空看看 awk  自己知道的只是皮毛 哎哎哎哎哎 4楼 也谢谢你
