First I'd like to say that raman1605 is correct: maybe your and the cronjobs rights are different and that the script is able to read/write to/from some logfiles doesn't mean the cron-job is able to do the same. That doesn't *need* to be a problem, but it could very well be one.

I have no idea. The best thing you can do to analyze that is to take a snapshot of your own environment by issuing

env > env.file

and look what stands there. Then put into your script everything from there that you think might be necessary, try it again, if it fails add some more, etc., until your script is running.

It is a good idea, though, to create a "standard-function" which sets your scripts environment. You can use this funtion over and over again for all your scripts and if something is missing there you could modify it and all your scripts will benefit. This could look like:

Code:
# save this as /usr/local/lib/ksh/stdenv

if [ -z "$NEVER_USE_THIS_VAR" ] ; then
     unset ENV
     typeset -x PATH='/bin:/usr/bin:/usr/local/bin'
     typeset -x FPATH='/usr/local/lib/ksh'
     # ... many more declarations, whatever you need ....

     NEVER_USE_THIS_VAR="kilroy_was_here"
fi

Now your scripts would start like:

Code:
#! /bin/ksh

. /usr/local/lib/ksh/stdenv         # set the standard environment

typeset -i somevar=0                # set some local variables

# ... etc., etc.

exit 0

apticron(1)						      General Commands Manual						       apticron(1)

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.
