Change Default Editor

Ubuntu and Linux Mint use nano as their default editor. You’ll see it if you try to edit crontab or visudo. Now, there’s nothing wrong with nano, but I prefer using vim instead. Here’s how to change the default editor.

sudo update-alternatives --config editor

You’ll be prompted to change the default editor.

There are 4 choices for the alternative editor (providing /usr/bin/editor).
 
  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /bin/nano            40        auto mode
  1            /bin/ed             -100       manual mode
  2            /bin/nano            40        manual mode
* 3            /usr/bin/vim.basic   30        manual mode
  4            /usr/bin/vim.tiny    15        manual mode
 
Press <enter> to keep the current choice[*], or type selection number:

Type 3 to choose vim basic.

Timedatectl

Here’s another way of setting your server’s timezone. See all the options under North America.

timedatectl list-timezones | grep -i America

Set timezone.

timedatectl set-timezone America/New_York

To check.

date

Restart cron if needed.

systemctl restart cron.service
