Remove the usage of cat. Replace the shell process with awk with 'exec'. Also use a generic shell because no bash specific features will be used.

# This example script parses /etc/resolv.conf to retrive DNS information.

# In the interest of keeping the KVP daemon code free of distro specific
|
|
# information; the kvp daemon code invokes this external script to gather
|
|
# DNS information.
|
|
# This script is expected to print the nameserver values to stdout.
|
|
# Each Distro is expected to implement this script in a distro specific
|
|
# fashion. For instance on Distros that ship with Network Manager enabled,
|
|
# this script can be based on the Network Manager APIs for retrieving DNS
|
|
# entries.
