我在一个文件中有数百万条记录，看起来像这样

echo "NEW Cell"
grep "2553,24" out.2A25.20090308.64436.7.HDF.txt.text = 22.58   5.39  82.09 237
echo "NEW Cell"
grep "2555,20" out.2A25.20090308.64436.7.HDF.txt.text = 24.72   5.58  82.05 237
echo "NEW Cell"
grep "2557,20" out.2A25.20090308.64436.7.HDF.txt.text = 19.75   5.62  82.11 170
grep "2557,21" out.2A25.20090308.64436.7.HDF.txt.text = 24.34   5.58  82.13 120
grep "2558,22" out.2A25.20090308.64436.7.HDF.txt.text = 22.2   5.57  82.19 120
echo "NEW Cell"
grep "2560,22" out.2A25.20090308.64436.7.HDF.txt.text = 24.69   5.62  82.25 160
grep "2561,23" out.2A25.20090308.64436.7.HDF.txt.text = 24.74   5.60  82.30 120
echo "NEW Cell"
grep "2560,24" out.2A25.20090308.64436.7.HDF.txt.text = 19.38   5.54  82.30 170
echo "NEW Cell"

现在我想删除带有“grep”的行，条件是它是包含“New Cell”的行之间的唯一行。也就是说，如果新单元格之间有一行 grep，则应删除该行。

这个怎么做？

我的输出应该是这样的，

echo "NEW Cell"
grep "2557,20" out.2A25.20090308.64436.7.HDF.txt.text = 19.75   5.62  82.11 170
grep "2557,21" out.2A25.20090308.64436.7.HDF.txt.text = 24.34   5.58  82.13 120
grep "2558,22" out.2A25.20090308.64436.7.HDF.txt.text = 22.2   5.57  82.19 120
echo "NEW Cell"
grep "2560,22" out.2A25.20090308.64436.7.HDF.txt.text = 24.69   5.62  82.25 160
grep "2561,23" out.2A25.20090308.64436.7.HDF.txt.text = 24.74   5.60  82.30 120
