i think problem is that maldet must run as root and the process i have used to run script as root

#!/bin/bash
echo xxxx| sudo -S sudo maldet -a /usr/bin > $HOME/maldetlog
is not working and ideas
this has been working on most scripts i have used over the years

so if i run in terminal it works but not in crontab

Use full paths to executables and files

[Holger_Gehrke]

If you want to execute a cron-job with root permissions, don't use sudo inside a user crontab (passwords in scripts are double-plus-ungood, mkay?). Use the root crontab.

Also according to the readme of maldet at rfxn.com (search for '.: 10'), it already installs a cron job by dropping a script in /etc/cron.daily/, which should be running as root.
