crontab

[Thibaut]

Hi

I try to use the crontab.
When I'm logged as root I enter "crontab -e"
Then I past "*/15 8-18 * * 1-5 parse.sh 2>/dev/null 1>/dev/null"
Then I exit and have the message : "crontab: installing new crontab"

When I'm logged as root I can execute normaly : "./parse.sh"

Where I am wrong ?

For testing, you should NOT redirect stdout or stderr.  That way, you
can see what it's doing.  After it's working correctly, *then* you can
discard the output.

Normal.

Note that (1) you're not passing the same command line as the crontab,
and (2) you're not in the same working directory as the crontab.  You
probably don't have the same $PATH either.

Likely, you need to make the crontab line something like this:

*/15 8-18 * * 1-5 /root/parse.sh

Note the explicit path.  Also, parse.sh might need to do a "cd /root"
so that it's in the directory it wants to be in.

Try making that "/root/parse.sh >/dev/null 2>&1" and it'll probably
be OK.

You have to put the full PATH to parse.sh, that's to say, for 
instance, /root/parse.sh

By the way, it's not a good idea to redirect the output to /dev/null, if 
something didn't work you would not be able to notice it.
All the best.
