Linux file Delete recovery operation by mistake

Objective

As a multi-user, multi-tasking operating system, the files under Linux are hard to recover once they are deleted. Although the delete command only deletes the file nodes, it does not really erase the contents of the file, but other users and some processes that have write actions will soon overwrite the data. However, for home use of Linux, or mistakenly delete files after timely remediation, or can be restored

First, with the Operation SECURECRT remote to the operating system, check the current system version number, and file system format
