Note that your crontab line states: # min hr dom mon dow command > * 04 * * * /home/titanus/scripts/web-log >> /dev/null 2>&1 That is, every minute during hour 4, on every day of every month (that being every day of the week), the command is run. Presumably, webalizer writes its output to the same place each time, so that is why you're only seeing the output of the 4:59 run. Try changing your crontab to read: # min hr dom mon dow command 0 04 * * * /home/titanus/scripts/web-log >> /dev/null 2>&1 This will run at 4:00 every day, and is probably what you meant.
