Script not working if crontab scheduled

Hi all,

I'm working to a script with /bin/bash shebang.
The script works perfectly if I run from command line.

The script runs under a non root user and inside the commands are set with sudo command in a such a way they can be run under root, for example (first rows of the script):
Code:
#!/bin/bash

#Command directory di NNM###

dir_nnm=/opt/OV/bin
dir_nnm_psg=/opt/OV/nonOV/Postgres/bin


### Ricavo il nome del sec group custom ####


secgroup_name="`sudo $dir_nnm_psg/psql -d nnm -U postgres -tc "select name from public.nms_sec_group" | egrep -iv "default|unresolved" | sed -e 's/^[ \t]*//'`"


I'd like to run in crontab under that non root user but when it starts under crontab the variables are set to empty.

Why this behaviour?

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
