UNIX for Dummies Questions & Answers

Hi All,

new to the forum and new to Unix but I have an issue which is annoying on a new level. I have included a short and full version for anyone needing more information.

Short Version

I am running a set of scripts that work and run fine. one of the scripts arranges the first script to run the day after at 19:00. The scripts run fine and I have even at 9am in the morning, set the first script to run at 3PM and it works yet 7PM comes around and the script doesn't run.

Full Version

I'm trying to schedule scripts to run the following tasks at 7PM in the evening.

Snapshot all servers
Export all snapshots to storage
Delete all snapshots
Re-Schedule the job for the following day.

I just want to start by saying this is the first time I've done anything like this and I understand that what I've created is incredibly basic and could be done 1000% times easier but for that I need more knowledge and I really need to get this working before I can develop the process a bit more.

so here is how I'm doing it. I have 3 scripts which are as followed


these all work fine and do what I need them to do. I have even at 9AM set the backups script to run at 3PM in the afternoon and it works fine and the new job is created fine. It seems that the script will not run at 19:00 and I have no idea why.

As I said before this is the first time I've used Unix and have no knowledge of troubleshooting.

If someone could suggest a possible reason to this happening or point me in the right direction of finding out why its happing I would be hugely grateful.

Thanks
Del

Since you dont show us the code, it will be difficult to help you... And we dont know on what system you are running ( OS - version ) and shell you are using...

this is first script that's is ran

Code:

 #Schedule Next Backup Job - re-run this script
sh < /Scripts/Schedule_Job.txt
 #Run Script to Perform Backups
sh < /Scripts/Run_Backup.txt

which runs fine through the day.

it's running through the command line in Citrix XenServer 6.2.

I've just had a thought though. I'm setting this to run through XenCenter which is then left open all day. I wonder if I set it off from the host itself it might work.

as I said the scripts run fine while I'm sat here just not when I have gone home.

Then you definitely should not go home any more!

Why don't you leave the scheduling to cron and have it run just the backup script every day at 19:00h?

Code:

crontab -e                                # edit your crontab file
0 19 * * * /Scripts/Run_Backup.txt        # add this line to the file

thanks this helped! the posts I seen about cron said the command was "cron -e" which didn't work. i'll see if that makes it work
