If you accidentally delete important files, you can also copy the files from the First Aid disk to the hard disk. For example, if the file/bin/login is deleted and the system cannot run properly on the logon page, you can start the system with an emergency disk group and install the hard disk file system in the/mnt directory, run the following command:

# Cp-a/bin/login/mnt/bin

The "-a" option is used to tell cp to maintain the object access permission during copy. Of course, this method cannot be used if the basic file to be deleted is not in the "First Aid disk group. If you have performed a system backup before, you can only use the previous backup to restore it.
