find and remove multiple file using linux command

Question

I have a directory named classes which contains a lot of sub-directories -

classes  
  |-security  
  |-registration  
  |-service  
 ....  

Each of these directory contains a lot of java files and their compiled classes files. I want to remove all the class file.

Going to classes directory I can list out all the class file using find command -

$ find . -name *.class  

Is there any command in linux to remove all the classes file under the classes directory.

Answer 1

The usual answer uses the -exec option of find :

find . -name "*.class" -exec rm {} \;

Be sure to quote the wildcard, to ensure that it is passed into find (rather than globbed by the shell, first).

For further discussion, see these questions:

• Command line: piping find results to rm
• Linux why can't I pipe find result to rm?

Answer 2

将xargs与管道衬里配合使用-

$ find . -name *.class | xargs rm *
