That seems to do exactly what I wan't, it's just not writing it to the file (my file named phonebook).
Code:
echo "Enter the name of the employee, to change their on-call day: "
read name
echo "enter new on call day: "
read newday
days=`grep $newday phonebook | wc -l` #This is to check availability day
if [ $days -ne 0 ]
then
echo "Sorry there is already an employee on call for that day"
exit
else
awk -v N=$name -v D=$newday '$0 ~ N { $NF=D; print $0 } ' phonebook
fi
echo "Success";;I changed the on call day from Wed to Sun and it came up and showed
Henry Test 000-000-0000 Sun
But it didn't write it to the file. Im not familiar with awk, but could I make the awk line a variable to use to add to the file?
like:
add = awk -v N=$name ..... etc
echo "$add" >> phonebook
or would that not work?

OCF_HEARTBEAT_SFEX(7) OCF resource agents OCF_HEARTBEAT_SFEX(7) NAME
ocf_heartbeat_sfex - Manages exclusive access to shared storage using Shared Disk File EXclusiveness (SF-EX) SYNOPSIS
sfex [start | stop | monitor | meta-data | validate-all] DESCRIPTION
Resource script for SF-EX. It manages a shared storage medium exclusively . SUPPORTED PARAMETERS
device Block device path that stores exclusive control data. (required, string, no default) index Location in block device where exclusive control data is stored. 1 or more is specified.

(optional, integer, default 1) monitor_interval Monitor interval(sec). Default is 10 seconds (optional, integer, default 10) lock_timeout Valid term of lock(sec). Default is 100 seconds. The lock_timeout is calculated by the following formula. .sp lock_timeout = monitor_interval + "The expiration time of the lock" .sp We suggest 90 seconds as a default value of the "The expiration time of the lock", but you should change it in consideration of access delay to the shared disk and the switch time of the multipath driver. .sp The lock timeout have an impact on start action timeout because start action timeout value is calculated by the following formula. .sp start timeout = collision_timeout + lock_timeout + "safety margin" .sp The "safety margin" is decided within the range of about 10-20 seconds(It depends on your system requirement). (optional, integer, default 100) SUPPORTED ACTIONS
This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 120s. stop Stops the resource. Suggested minimum timeout: 20s. monitor Performs a detailed status check. Suggested minimum timeout: 10s. Suggested interval: 10s. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 5s. EXAMPLE
The following is an example configuration for a sfex resource using the crm(8) shell: primitive p_sfex ocf:heartbeat:sfex params device=string op monitor depth="0" timeout="10s" interval="10s" SEE ALSO
