How to undo rm -rf? [closed]

How we can undo rm -rf command ? For example, I have Application folder. And I have remove it by

rm -rf Application

But it was my mistake and want to recovery or want that Application Folder. But its not in Trash folder. What should I do now ? Is there any command undo rm -rf

With your backup tapes.
Unix does not protect you from doing bad things. You specified the recursive & force flags, it assumed you knew what that would mean, and did what you asked.

If the data is important power the machine off immediately (seriously, rip the plug out of the wall before the operating system writes something in that "free" space and destroys your data) and contact a data retrieval company.
(The fact that you're asking this question indicates to me that you lack the experience required to attempt recovery yourself - I'm not going to send you down that particular rabbit hole.)

If the data is not important, try a utility like unrm.
