I'm trying to make a full backup, for it followed the following steps:

1 Open a console, and navigate to the /opt/novell/sentinel/bin directory as the novell user.

2 Enter backup_util.sh, along with the necessary parameters for the data that you want to backup

I am using the following syntax:
sh backup_util.sh -m backup -c -e -i -l -r -w -s -u admin -x <mypassword.txt> -f /var/opt/novell/sentinel/data/<my_full_backup>.tar.gz

but it gives me in response:

sh: mypassword.txt: No such file or directory
