我有一个这样的文件:
1000_Tv178.tif,34.88552709
1000_Tv178.tif,
1000_Tv178.tif,34.66987165
1000_Tv178.tif,
1001_Tv180.tif,65.51335742
1001_Tv180.tif,
1002_Tv184.tif,33.83784863
1002_Tv184.tif,
1002_Tv184.tif,22.82542442
1002_Tv184.tif,
我怎样才能使用简单的 Bash 命令使它像这样?:
1000_Tv178.tif,34.88552709
1000_Tv178.tif,34.66987165
1001_Tv180.tif,65.51335742
1002_Tv184.tif,33.83784863
1002_Tv184.tif,22.82542442
换句话说,我需要从第二行开始每隔一行删除一次。
谢谢!
