Shell Scripts to Ansible

During a recent client visit, we were asked to help migrate the following script for deploying a centralized sudoers file to RHEL and AIX servers. This is a common scenario which can provide some good examples of leveraging advanced Ansible features. Additionally, we can consider the shift in approach from a script that does a task to describing and enforcing the state of an item idempotently.

Here is the script:

#!/bin/sh

# passed status/return code

clean_exit()
{
cd /
test -f "$tmpfile" && rm $tmpfile
exit $1
}

#Set variables
PROG=`basename $0`
PLAT=`uname -s|awk '{print $1}'`
HOSTNAME=`uname -n | awk -F. '{print $1}'`
HOSTPFX=$(echo $HOSTNAME |cut -c 1-2)
NFSserver="nfs-server"
NFSdir="/NFS/AIXSOFT_NFS"
MOUNTPT="/mnt.$$"
MAILTO="[email protected]"

echo "Starting ${PROG} on ${HOSTNAME}" >> ${LOGFILE} 2>&1

if [ $runas -ne 0 ] ; then
