Changing default crontab editor

Question

I am trying to change the default editor from nano to vim.

I have run the following commands:

sudo update-alternatives --config editor

and

update-alternatives --config editor

Both now output:

  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    10        manual mode

I have restarted my ssh session and restarted sshd but crontab -e still opens in nano

What else do I need to do?

Answer 1

Just simply run select-editor, this will let you choose any editor you want.

Answer 2

Try your ssh session followed by

export EDITOR=vim

or possibly

export EDITOR=/usr/bin/vim.basic

The format of setting of the EDITOR variable depends on which shell you are using.

In Ubuntu you can set the EDITOR environment variable on logon by adding the above to the ~/.profile

Your SSH session will read a similar file (if it exists) on the remote host called ~/.ssh/environment. This has to be specifically defined by the ssh daemon config. See man sshd_config and look for PermitUserEnvironment for more details.

Answer 3

If you only want to choose the editor temporarily, you can do the following

EDITOR=nano crontab -e

If you want do this for root user then:

sudo EDITOR=nano crontab -e

This sets the EDITOR environment variable for the command

Answer 4

My personal preference...

cd /bin
mv nano nano_must_die
ln -s /usr/bin/vim nano

Answer 5

From "man crontab":

   The -e option is used to edit the  current  crontab  using  the  editor
   specified  by  the  VISUAL  or EDITOR environment variables.  After you
   exit from the editor, the modified crontab will be installed  automati‐
   cally.  If  neither  of  the environment variables is defined, then the
   default editor /usr/bin/editor is used.

Perhaps you have the EDITOR enivronment variable set to nano?

Answer 6

On my Ubuntu 12.04 computer, crontab uses the ~/.selected_editor file, which contains the path of the selected editor. Edit it:

nano ~/.selected_editor

I have edited it directly or used select-editor, which is a script to do the same thing. Edit the following line:

SELECTED_EDITOR="/usr/bin/vim.basic" 

IHMO people should not be changing anything in /etc or /bin to do this. It is a user level thing, not a system wide task.

Answer 7

In addition to checking that the environmental variable EDITOR is set correctly, you should also check to make sure the variable VISUAL is also set correctly.

VISUAL will override EDITOR

From the documentation:

The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables.

For example, if you set

$ export EDITOR=vim
$ export VISUAL=nano

Then the command crontab -e will still open in nano.

You should set both to be the editor of choice, ala vim for me:

$ export EDITOR=vim
$ export VISUAL=vim

Then the command crontab -e will open in vim.

Answer 8

I've had the same problem - crontab -e relies on select-editor, visudo relies on the config of "alternatives"

My solution:

run both commands as root

# update-alternatives --install /usr/bin/editor editor /usr/bin/sensible-editor 50

# select-editor 

Select an editor.  To change later, run 'select-editor'.
  1. /bin/nano        <---- easiest
  2. /usr/bin/sensible-editor
  3. /usr/bin/vim.basic
  4. /usr/bin/vim.tiny

Choose 1-4 [1]: 3

Answer 9

After trying the answers above, the only thing that worked for me (in Debian strech) was to remove ~/.selected_editor by running:

rm ~/.selected_editor

And then select the new editor next time you run crontab -e.

Answer 10

I was having difficulties with select-editor and update-alternatives, my solution was to simply edit the link:

1. sudo rm /etc/alternatives/editor
2. sudo ln -s /usr/bin/vim /etc/alternatives/editor

editor now opens Vim
