Question

I want to set up TWiki to automatically run the statistics command as a cron job.

I created a cron job in Webmin to run /var/www/twiki/bin/statistics.

When I run this command, either as apache (the usual TWiki-accessing user) or as root, I get this error:

Can't locate TWiki.pm in @INC (@INC contains: ../lib . /usr/lib/perl5/5.6.1/i386-linux 
/usr/lib/perl5/5.6.1
/usr/lib/perl5/site_perl/5.6.1/i386-linux

/usr/lib/perl5/vendor_perl) at /var/www/twiki/bin/statistics line 29.
BEGIN failed--compilation aborted at /var/www/twiki/bin/statistics line 29.

I guess that means it can't find TWiki.pm, despite that it is actually in ../lib relative to the folder the command is located in.

So I changed the command to run cd /var/www/twiki/bin/;./statistics.

This produced the following output:

TWiki: Create Usage Statistics

End creating usage statistics

And this seemed to work. My only concern is those "No such file or directory" errors.

Did I set up the cron job properly, and if not, what is the correct way?

• TWiki version: Dec 2001
• Perl version: 5.6.1
• Web server & version: Apache 1.3.23
• Server OS: Redhat 7.3
• Web browser & version:

Answer

You do need to include the cd command in the cron job, as mentioned in the manual

As for the '%FILENAME%' thing, I'm not sure what causes this, but it's always a good test to see if you get this when running statistics from the bin directory in the shell.

I was looking at the install instructions and didn't see it. The manual entry is in TWikiSiteTools#WebStatistics_Site_Usage_Log.

I ran the command in the shell and still got the '%FILENAME%' errors. But the stats seem OK, so I'm not too concerned as it's a home system.
