crontab

Hi,

I edited crontab and tested it to make sure it is doing exactly what I want. Then I logged off.

The next day I found out that the crontab didn't run at night as it should, but after I logged on crontab started to work !

Do I need to keep my user logged on all the time to let crontab run, or am I missing something?

No, that's the whole point of crontab.

What is the crontab entry for your job?

it is very simple - just to get disk free info into a history file :

$ crontab -l

0 6-7 * * 1-5 echo ============== >> /home/alf/df_history.txt
0,30 8-18 * * 1-5 /home/alf/df_history

So, when I checked the file, it missed the two lines (in the echo ===== command) and the df_history script at 8 (as I logged on at about 8:05).

From this, I would expect to see two "===================" lines in df_history.txt (assuming the file was empty the previous evening).

You haven't redirected the output of df_history to the txt file. Is that coded in the script itself? Did you use an absolute pathname?

Yes, actually it is working now without any problem. (it dumps every 30 minutes output of df -k to the history file with date stamp).

I guess I'll try to log off now for while and see if it stopped during that period or not.
