Receiving mail from crontab
 

Hi All,

I am getting a bit confused from the messages that I receive in my gmail
account sent from my crontab.

First, is related to the title which is:

Cron <root@mylaptop> test -x /usr/sbin/run-crons && /usr/sbin/run-crons

I am not sure what this "test -x" part represents?


The second question is related to the output of chkrootkit, which is run by
the cron.weekly and emails stuff that don't make much sense to me:

==========================================

Now I happened to notice that the above legible references to vlc are from the
"services discovery" list that the vlc player shows under Media/Services. Not
sure what they are doing in chckrootkit ... is it telling me that it just
scanned all such content? When I run it manually it looks just the same and
follows a long output following "Searching for suspect PHP files..." I am not
sure I understand why chkrootkit is emailing these to me and if I need to do
something about it.

The `test -x <ffile>' part means "Test that <file> is executable."
and, implicitly, tests that the file exists. Sorry not to be more
helpful.

It means: If /usr/sbin/run-crons is executable, execute it. It could also
be written as
[ -x /usr/sbin/run-crons ] && /usr/sbin/run-crons
or
f=/usr/sbin/run-crons
if [ -x $f ]
then
$f
fi


No idea about your other question, though.
