Crontab not working
Here

crontab -e:
30 18 * * * php bookproxy/followup.php
30 18 * * * php bookproxy/expire_needers.php

Well? Those scripts aren't executing at 6 30 PM or ever.

doing 'man crontab' yields:
Quote:
The shell is invoked from your $HOME directory with an arg0
of sh. Users who desire to have their .profile executed must
explicitly do so in the crontab file. cron supplies a
default environment for every shell, defining HOME, LOGNAME,
SHELL(=/bin/sh), TZ, and PATH. The default PATH for user
cron jobs is /usr/bin; while root cron jobs default to
/usr/sbin:/usr/bin. The default PATH can be set in
/etc/default/cron; see cron(1M).

If you do not redirect the standard output and standard
error of your commands, any generated output or errors will
be mailed to you.


check your path(s) [both php and its arguments] are accessible from cron. If not provide ABSOLUTE pathnames and/or "source" your profile.

Hello and thank you for replying. I read the man page but

Echoing $HOME gives me the existing directory, which I am able to execute PHP from the shell. Echoing $PATH results:
/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/local/msql/bin:/usr/local/mysql-3.21.29-gamma/bin:/usr/games:.

I assumed that since I was able to execute PHP from my home directory, cron would be able to. Any idea?

you executed 'php' from the shell prompt. cron's PATH is different

also 'bookproxy/followup.php' and 'bookproxy/expire_needers.php' are RELATIVE paths. Relative to what?

I'd consider supply ABSOLUTE pathnames anywhere in cron AND/OR explicitely "sourcing" your user "profile" from cron as well. Something like this - with mnemonic pathnames:

Quote:
30 18 * * * [ -f $HOME/.profile ] && . $HOME/.profile && /path2php/php /path2book/bookproxy/followup.php

Thank you for the example but I have some questions. Firstly, I do not have .profile, at least not in the home directory. What should be in there, to be sourced?

The paths are relative to $HOME. Is this neccessary to put before the relative paths of those .php docs?

what shell are you using? csh/tcsh/bash???
do you have '.cshrc'?

these are the shell 'startup' files that set your environment.

yes.

try debugging your cron entry like so:
Code:
30 18 * * * [ -f $HOME/.profile ] && . $HOME/.profile && /path2php/php /path2book/bookproxy/followup.php > /tmp/cron.log 2>&1


check '/tmp/cron.log' AFTER the cron entry is to be executed.

Crontab now contains:
Quote:
58 10 * * * [ -f $HOME/.bash_profile ] && . $HOME/.bash_profile && /usr/local/bin/php $HOME/bookproxy/followup.php > $HOME/cron.log 2>&1


Yet at 10:58 nothing happened (no output to log). Checked the system time with 'date' just to make sure.

wondering if ANYTHING gets executed from your cron.

debug it one step at the time:

58 10 * * * /bin/ls $HOME > /tmp/cron

then try:
58 10 * * * [ -f $HOME/.bash_profile ] && $HOME/.bash_profile && /bin/ls $HOME > /tmp/cron

also read 'man crontab':

Quote:
crontab Access Control
Users: Access to crontab is allowed:

o if the user's name appears in /etc/cron.d/cron.allow.

o if /etc/cron.d/cron.allow does not exist and the
user's name is not in /etc/cron.d/cron.deny.

Users: Access to crontab is denied:

o if /etc/cron.d/cron.allow exists and the user's name
is not in it.

o if /etc/cron.d/cron.allow does not exist and user's
name is in /etc/cron.d/cron.deny.

o if neither file exists.

Note that the rules for allow and deny apply to root only if
the allow/deny files exist.

The allow/deny files consist of one user name per line.

No response. I am going to mail the sysadmin. Will let you know if that doesn't fix things, thank you very much for your help and patience!
