I think the biggest problem is here is the misconception about what sudo does and what it doesn't:

sudo will run a command as another user (usually as root), but: it is NOT a shell and neither it is a shell replacement!

I wonder why the user account you use to run the script is not allowed to run the commands within the script. If the commands are privileged in nature then use a privileged user which can run them natively. call the whole script via sudo instead of embedding sudo-enabled calls into the script.

If you really need to do it the way you tried use su instead of sudo and use sudo only to call the script:

Code:
#! /bin/sh
[...]
su - <user> -c <your command along with options>
[...]

Code:
user@sys # sudo <scriptname>

I hope this helps.

NAME
mtailrc - Configuration file for monkeytail DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed. Best explained with an example: <group testgroup> prefix 'server2: ' sudo yes <file> filename /var/log/apache2/access.log prefix 'server1: ' host server1.example.com </file> <file> filename /var/log/apache2/access.log host server2.example.com sudo no </file> </group> OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block. filename filename filename defines the filename for this block. host remote-host (optional) host defines that this block's file is to be tailed on a remote server. sudo yes|no|1|0 sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files (in both cases you will potentially be prompted for your password). prefix "string: " prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
