Replacing Tab characters in java files with 4 spaces?

前提是你 提交于 2020-01-06 19:34:40
问题 I've had a search about here, and nothing seems to be on the topic of replacing tab characters, I was wondering if anybody can suggest to me any easy ways to replace the tab characters with 4x 'space' characters in over 5,000 files!
