nano: Open a file and create a backup file (`path/to/file~`) on save.
$ nano --backup ${filename}
try on your machine
The command "nano --backup ${filename}" is used to open a file in the Nano text editor and create a backup of the original file before making any modifications. Here's a breakdown of each part of the command:
- "nano" is the command to launch the Nano text editor.
- "--backup" is an option for the nano command that instructs it to create a backup file before modifying the original file.
- "${filename}" is a placeholder for the actual filename. You need to replace "${filename}" with the desired filename to open in the editor.
By using this command, you can edit the specified file in the Nano text editor, while also having a backup of the original file in case you need to revert any changes.
