When I am trying to use crontab in dom0, I am having trouble.
I type:
sudo crontab -e
I don’t get an option to use nano and it goes right to vim which I don’t understand much of
then I try to type @reboot and the @ symbol is not accepted “E348: No string under cursor”
What is going on?
You certainly do not know how to use the editor vi?
Press i before typing text, once you are done, press escape, then :wq to save and quit.
Otherwise, you could edit the crontab with nano, which may be easier to get into?
Hi wmrom2
How about:
sudo --preserve-env=EDITOR crontab -e
?
sadly it was actually this
nano ruined me
Thanks!
This command line also work, in case you are not sure what EDITOR is or you want a specific editor for your crontab.
sudo env EDITOR=nano crontab -e
Since vi is one of the few editors included in (almost?) every Unix-like system, I would recommend getting a minimal understanding of the “Command mode” and “Insert” … and how to switch between them … including the :q! (“Quit vi without saving changes!”)
i know, i should
i’m such a freak for being a qubes user and being so limited in my linux understanding
i keep wanting to go back to nano but power users use vi
i’ll man vi one day, promise
When I landed my first job, my new colleagues gave me one of these:

I’m [still] not a power user of vi – so the mug has followed me ever since …
Basics -
i to Enter Insert Mode, where you enter text
Esc to exit Insert Mode, and enter Command Mode
In Command Mode-
:w to Write the document
:q to Quit the document
:wq to Quit the document, saving changes.
:q! to Quit the document, ignoring changes since last write.
I think that this legendary post is one of the clearest guides to using Command Mode in vi.
I never presume to speak for the Qubes team.
