Linux system prevents accidental deletion of files

1.Preface

Once Upon a while, a rm-rf/useless/* command took out the files we needed, and the entire system was killed ,

This is not with tears.

such as the use of the RM command mistakenly delete the file, we will notice, but we can not guarantee that it will not happen, after all, there is always an accident, then for this situation we are not bound without policy, no! We have a corresponding solution, that is, the use of trash-cli.

1.1 Trash-cliIntroduction

TRASH-CLI provides a set of command-line Recycle Bin tools. In the GNOME environment, this command-line recycle bin is unified with the Gnome Recycle Bin, and the deleted files will go to the Recycle Bin, both at the command line and in the graphical environment.

1.6 Trash-cliTool Usage Examples

Example 1: Delete the/etc/issue file and restore it.

[Email protected] ~]# Cat/etc/issuecentos release 6.6 (Final) Kernel \ r on an \m[[email protected] ~]# Rm/etc/issue[[ema Il protected] ~]# cat/etc/issuecat:/etc/issue:no such file Ordirectory[[email protected] ~]# Cp~/.local/share/trash/fil Es/issue/etc/[[email protected] ~]# Cat/etc/issuecentos release 6.6 (Final) Kernel \ r on an \m

Example 2: RM-RF/* recovery performed by mistake

# When we execute the rm-rf/* operation even if the CTRL + C Terminate operation immediately deletes part of the content
