标题: awk输出$3之后的所有域
请问如何用awk输出$3之后的所有域
cat aaa.txt | awk '{print $1"\t"$2"\t"$3????}'
谢谢

awk '{for (i=3;i<NF;i++){printf $i"\t"} print $NF}'

如果只是单纯的删除前两个域，分隔符也是单一字符，cut -d' ' -f3- urfile会更简洁一些。

你的写法有问题吧。

呃，没看清楚楼主需求。把3换成4就成了。
多谢黑哥提醒～：）

哎，不对啊黑哥，再看楼主给的例子，就是第三个域以及其后的嘛～ - -

其实大家没有理解楼主的意思
他是想输出$1 \t $2 \t 然后其他所有域
并不只是想输出第三个域之后的。
