我想删除第8列（编号200、210、120）小于200的ROWS，但必须保留新单元格。我已经尝试过像这样的awk：

awk '{if ($8 >= 200) print $0}' CSWoSpix.apr2009.sh >OUT1

但它并没有保留回声“New Cell”的线条。

答案1

要打印字段 8 大于 200 或包含短语 的行New Cell，请尝试：

awk '{if ($8 >= 200 || /New Cell/) print $0}' filename

因为 print 是 awk 的默认操作，所以上面可以简化为：

awk '$8 >= 200 || /New Cell/' filename
