Debian crontab switches the Default Editor nano to Vi.

The default crontab editor used by Debian systems is nano, which is inconvenient to use. How can we switch between them?

Root @ debian :~ # Update-alternatives -- config editor
There are 8 choices for the alternative editor (providing/usr/bin/editor ).
Selection Path Priority Status
------------------------------------------------------------
0/usr/bin/joe 70 auto mode
* 1/bin/nano 40 manual mode
2/usr/bin/jmacs 50 manual mode
3/usr/bin/joe 70 manual mode
4/usr/bin/jpico 50 manual mode
5/usr/bin/jstar 50 manual mode
6/usr/bin/rjoe 25 manual mode
7/usr/bin/vim. basic 30 manual mode
8/usr/bin/vim. tiny 10 manual mode
Press enter to keep the current choice [*], or type selection number: 8
Update-alternatives: using/usr/bin/vim. tiny to provide/usr/bin/editor (editor) in manual mode.

After entering the command, you will be prompted to select it. Select it based on your preferences. Here I select the VI editor and enter 8.
Now the crontab editor is changed to VI.
If the switchover is not successful, restart the service manually:/etc/init. d/cron restart.
