查找子目录并删除不包含特定字符串LINUX的文件

Question

Given a main path ./class and within class are subdirectories student1 , student2 , student3 ... student100. within these subdirectories are other sub-directories history , geography , Math . Each of these subdirectories have hundreds of files in them. I want to KEEP all files that have a string pass in Math ONLY without affecting files in other subjects. So far I can cd to Math and do this:

find . -type f -print0 | xargs --null grep -Z -L 'pass' | xargs --null rm

But it is ineffective to cd to Math in each of the 100 subdirectories and rm unwanted files.

How can one grep only Math and execute the code above?

Answer 1

以下应该可以解决问题

for i in `find . -type d -name *Math* -exec find {} -type f -not -name *pass* \;`; do rm $i ; done
