My crontab file tells cron to run a certain shell script at 10:30 AM every day. The shell script backs up my database with mysqldump and then runs a sed script that does some editing of the backup file.
I have programmed the shell script to write an error message to a file I have in my home directory, ~/errorlog.txt, whenever it can't locate the backups directory. I looked in my errorlog file today and found the following messages:
Here is the script I used:
The content of the script is not important. I just put it there so you can see what I'm doing. You can skip over it if you don't want to read my sloppy code.
I think I have determined the problem: cron can only run programs when the computer is on and running. When it's asleep, certain things don't work. Obviously, there is no problem with the script, as it appears to have worked on the 10th. I think this is because I was using my computer at the time.
Do you think I diagnosed the problem correctly? Also, is there any way of working around the fact that I can't have my computer active 24/7?
