如何从所有文件中删除特定行？

Question

I want to delete all lines begin with 'sometext' from many files:

find . -name "*.php"|xargs -I {} sed -e '/^sometext/d' {}

But this put me output to console. How to modify this files directly?

Answer 1

使用sed的-i选项：

 sed -i -e '/^sometext/d' file

Answer 2

Tell sed to modify the files "in place":

find . -name "*.php" | xargs sed -i '' -e '/^sometext/d'

Note that the blank '' after -i is required, otherwise a new copy with a default suffix will be created.

Also note the pruning if your unnecessary -I in xaegs

Answer 3

您可以使用exec完成此操作：

find . -name "*.php" -exec sed -i '/^sometext/d' {} \;
