Question 8: You are attempting to edit your crontab file in the bash shell. Instead of getting your usual viinterface, you are presented with an unfamiliar interface. In order to have your editor of choice-vi-
what command must you type after exiting the unfamiliar editor?
A. EDITOR=vi
B. crontab=vi
C. crontab - e vi
D. env
Correct Answer: A
Explanation:
Set the EDITOR variable to vi.
Commands like `crontab -e` will use ed per default. If you'd like to use some better editor (like vi) you
can use the environment variable EDITOR:
# EDITOR=vi; crontab -e will open the users crontab in vi. Of course you can set this variable
permanently.
Incorrect answers
C: -e Edits a copy of the current user's crontab file, or creates an empty file to edit if crontab does not
exist. When editing is complete, the file is installed as the user's crontab file. If a username is given,
the specified user's crontab file is edited, rather than the current user's crontab file; this can only be
done by a user with the solaris.jobs.admin authorization. The environment variable EDITOR
determines which editor is invoked with the -e option. The default editor is ed(1). All crontab jobs
should be submitted using crontab. Do not add jobs by just editing the crontab file, because cron is
not aware of changes made this way.
