tc_mount

truecrypt -t  --non-interactive /dev/sdb1 -p "<my password>" -k "<key path>"


exit 0


script runs fine with SUDO, but I want it to run at boot or with with root without password (i.e. SUDOERS entry).

I added the below line to sudoers, but still no luck:
username ALL= NOPASSWD: /path/to/above/script
