发布时间：2020-12-15 22:50:09 所属栏目：安全来源：网络整理

导读：我想运行这些sed行： sed 's//1/1//1/g' file -i sed 's//2/2//2/g' file -i 在这样的文件上： chr9_paternal 126628489 126629719 616L7AAXX_HWUSI-EAS627_0005:1:1:1157:5733/1/1 0 + 126628489 126629719 255,0 2 19,57 0,1173chr20_paternal 34093

我想运行这些sed行：

sed 's//1/1//1/g' file -i && sed 's//2/2//2/g' file -i

在这样的文件上：

但文件很大,我不想读两遍.可以运行一次执行两条指令的sed代码吗？

解决方法

您可以使用-e在一个sed调用中执行多个表达式：

sed -e <expr> -e <expr> -i <file>
