Top Forums UNIX for Dummies Questions & Answers Using a script to modify the crontab Post 77366 by blowtorch on Thursday 7th of July 2005 01:11:36 PM

It is not necessary to use crontab -e to edit crontabs. You can directly do this:

echo "<entire_line_that_is_required_including_the_timings_and_commands>" >> /var/spool/cron/<crontab_file>

You will have to give the cron daemon a HUP signal after this. So if you are not someone who has root access, you will have to find someone that does.

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
