Wget

[Pommie]

Hi I am trying to run a cron job once a day but wget (which chat told me is the command type to use) is giving an error

This is the cron

wget -q -o /dev/null wwwDOTwindermerelodgeDOTco.uk/send/send.php
(I have amended the command in case any naughty peeps tried to execute it
This is the result

/bin/sh: /usr/bin/wget: Permission denied

If I just use the

wwwDOTwindermerelodgeDOTco.uk/send/send.php

command in the address bar it executes fine

Any ideas?

I believe there are various methods to do this. I use root instead of a url:
php /home/username/public_html/send/send.php
and have no problems.

I actually have my db connection and cron files above root for further protection, so they can't be run from a browser. i.e:
php /home/username/send/send.php

Hi Jon

Thanks that seems to have worked

To stop it sending me messages do I just add the /dev/null at the end?

Cheers John

Hi John, I think you append :
>/dev/null 2>&1
to the end to stop emails
http://wwwDOTadminschoice.com/docs/crontab.htm#Example

so : php /home/username/send/send.php > /dev/null 2>&1

Thanks

I am familiar with the "/dev/null" bit what does the "2>&1" bit do?

Cheers

John

Answering my own question

> /dev/null pipes standard output to a black hole
2>&1 send error message to the same place

1 is standard output, 2 is error output

So to have only errors sent (which is in fact what I want) I just use > /dev/null

See a very useful article here for more detail

Good article!

I actually want my emails, there has been a couple of instances where the cron jobs have stopped working. Something to do with a vps service stopping and not auto-restarting. Although this I understand has now been sorted, i still need to make sure that every day i get my 3 cron emails letting me know the scripts have been executed.
I am glad they are just daily though, if i received an email every 15 minutes i think i would need to blackhole them.
