如您所见，我想保留一个完全相同的标题.之后，我只想将前 9 列分开.如果我这样做，在 9 选项卡之后，测试的其余部分将成为第一列的一部分.
As you can see, there is a header which I want to maintain exactly the same. After that, I just want to tab separate the first 9 columns. If I do that, after the 9 tab, the rest of the test is going to be part of the first column.
谢谢！
推荐答案
默认情况下 sed s/.../.../ 仅替换第一次出现.因此，您可以重复此替换 8 次.在这里，我们也忽略了以 # 开头的行.
By default sed s/.../.../ replaces only the first occurrence. Therefore you can repeat this substitution 8 times. Here, we also ignore lines starting with #.
在 bash 中，可以使用大括号扩展 {1..8} 和 printf 进行重复.
In bash, repeating can be done by using the brace expansion {1..8} and printf.
printf -v cmd 's/ /\\t/;%.0s' {1..8}
sed '/^#/!'"{$cmd}" yourFile
对于普通的 sh 使用循环或长版本
For plain sh use a loop or the long version
sed '/^#/!{s/ /\t/;s/ /\t/;s/ /\t/;s/ /\t/;s/ /\t/;s/ /\t/;s/ /\t/;s/ /\t/;}' yourFile
