Introduction: How to recover a file after RM has deleted it. Personal knowledge is not yet common.

In the last two weeks, the code was deleted two times because of a mis-operation. But because of the time is relatively tight, it is directly re-written, and not using the recovery function.

1: The detailed method can be referenced in article A.

2: Edit Path CD ~/.BASHRC

3: Add code at the end of the file:

#replace RM with MV, use TRM to run true RM
Trash ()
{
MV [email protected] ~/.local/share/trash/files #注意, which can be defined in its own right. When you delete a file for a long time, remember to clear the folder.

}

Alias trm= "/bin/rm"

Alias rm= "Trash"

4: Reload. Bashrc:source. BASHRC
