how to get back my recent delete files?

Restoring your backup.

Chances are, you don't have a backup, you're pretty much S.O.L.

You have to be really careful when using the "rm" command in linux, make sure you are 100% sure that it's what you want. Note: There are ways to recover lost files, but it's a long and complicated process, and unless the files are absolutly mission critical, you probably don't want to do it.
