Data script execution differs in cron
I have the following script (MyScript):

#!/bin/sh
ps U erv | grep -v grep | grep -F "/usr/bin/collect -o 101"
echo "Result: $?"

When executed from the command line, I get
... (the line containing /usr/bin/collect -o 101)
Result: 0
(which is correct since collect is running)

When I put the script in cron with:
*/10 * * * * ./MyScript >>log.log

in log.log I get
Result: 1

What is wrong?
I tried to put the complete path for ps and grep, but I had the same result.
Could be because the command displayed by ps is truncated? How can I display it all?

Please help!

NAME

       apticron - Generate a mail listing packages which are pending an upgrade

SYNOPSIS

       apticron [--cron]

DESCRIPTION

       apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes -
       using apt-listchanges - to a configurable Email address.

       apticron is mainly intended for automatic notification of pending security updates but can also be used	in  many  other  situations  where
       timely updates are necessary.

       The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.

FILES

       /etc/apticron/apticron.conf
	      Configuration file, Email address to mail and profile for use with apt-listchanges are configurable.

       /etc/cron.d/apticron
	      Cron job for executing apticron daily.

       /etc/cron.daily/apticron
	      Fallback cron script for executing apticron (if no crond running or system down at designated time).

       /var/lib/misc/apticron.cron
	      Time stamp file used by apticron when invoked with --cron option.
