When a file is deleted using Ranger, that deletion is permanent. Instead, if you would like to delete files to Trash, then you can do that using the Trash-CLI set of tools.
Installing them is easy:
$ sudo apt install trash-cli
The tool we are interested in is
trash-put which deletes a file to the Trash. The Trash directory is usually
~/.local/share/Trash. Any key can be mapped in Ranger to this command for deletion.
For example, to map the
Del key to delete to Trash, add this to your
map <DELETE> shell -s trash-put %s
Tried with: Ranger 1.6.1, Trash-CLI 0.12.7-1 and Ubuntu 14.04
