One way is to use a control file for any "state" oriented scripts.
Create a directory in /var/tmp called "croncontrol"
Create a script called "disable" that accepts variables depending on the cronjob name (backup, reportmailer, etc).
This script will touch /var/tmp/croncontrol/backup or /var/tmp/reportmailer, etc.
Create a wrapper for your cron script (or add a line to the existing cron script) that checks for the file /var/tmp/croncontrol/backup (or mailer or whaterver). If the file exists, exit and do not run (although I'd recommend that it mail out that the script is not being run). If the file does not exist, proceed with the normal script function.
To enable the cron scripts to run again, write a simple script that accepts the same variables to rm the 'touched' file in /var/tmp/croncontrol.
Simple - but not terribly robust.
Thank you for suggestion. Will it be possible to guide sample scripts? Not much background on shell script writing. Regards

The operators would then have a script that would create/remove the lock file (where they have permissions to write). You could also implement that lock file logic into the backup script.
The danger in all of this is that if someone forgets to re-enable the backup script, backups won't be performed. I suppose you could also implement another job that would remove any lock file older than say 3 days.
Thank you Peterro, Can you suggest any sample script I can look into? Regards

Hello,

Hi, guys. I have two questions:
I need to write a script, which can show all the non-suspended users on system, and suspend the selected user account.

Is there a way to suspend (TSTP?) a job that is running in the background, _without_ first bringing it to the foreground and inputting Ctrl-Z from the keyboard?
IOW, something similar to issuing the shell's bg builtin command on a job ID to resume a job that is suspended in the background,... (2 Replies)

bcrontab
bcrontab(1) General Commands Manual bcrontab(1)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.
