Run this grep every 10 minutes and do something based on the output
OS : Red Hat Linux 6.4
Shell : Bash
We have a file called status.txt which will have only 1 line. The content will be the string "Processing" for most of the day.
I want to write a shell script (notify.sh) which will be executing a grep every 10 minutes .
Once the script is executed , it should do the following
1. run a grep command every 10 minutes and check if the content of status.txt is anything other than "Processing" .
2. If the status.txt file has anything other than the string "Processing" (ie. grep -v "Processing" ) then it should echo "Completed". Actually in my real business scenario If the status.txt has anything other than "Processing" then a mail needs to be send out using Linux's mail command. But, for our testing purpose an echo "completed" should do .
3. Stop the execution of the notify.sh script (exit) after grep command managed to find anything other than the string "Processing" and printed "Complete" .
Note: I don't this to be invoked via a cronjob because in my real world scenario this logic has to be incorported as a subsection of a much bigger script.

rhsmcertd(8) Subscription Management Certificate Daemon rhsmcertd(8)NAME
rhsmcertd - Periodically scans and updates the entitlement certificates on a registered system.
SYNOPSIS
rhsmcertd [--cert-check-interval=MINUTES] [--auto-attach-interval=MINUTES] [--now] [--debug] [--help]
Deprecated usage
rhsmcertd [certInterval autoattachInterval]
DESCRIPTION
Red Hat provides content updates and support by issuing subscriptions for its products. These subscriptions are applied to systems
(machines). Red Hat Subscription Manager is a tool which allows administrators to manage those subscriptions by registering systems and
people, applying subscriptions, and viewing subscriptions.
When subscriptions are applied to a system or when new subscriptions are available, the subscription management system issues that machine
an X.509 certificate which contains all of the details of that subscription. The rhsmcertd process runs periodically to check for changes
in the subscriptions available to a machine by updating the entitlement certificates installed on the machine and by installing new enti-
tlement certificates as they're available.
At a defined interval, the process checks with the subscription management service to see if any new subscriptions are available to the
system. If there are, it pulls in the associated subscription certificates. If any subscriptions have expired and new subscriptions are
available, then the rhsmcertd process will automatically request those subscriptions.
This rhsmcertd process invokes the certmgr.py script to perform the certificate add and update operations.
Both the certificate interval and the auto-attach interval are configurable and can be reset through the rhsmcertd daemon itself or by
editing the Subscription Manager /etc/rhsm/rhsm.conf file.
rhsmcertd is started with the machine, by default, and is always running in the background.
OPTIONS -h, --help
Prints the specific help information for the given command.
-d, --debug
Records more verbose output to the /var/log/rhsm/rhsmcertd.log log file.
-n, --now
Runs the rhsmcertd scan immediately, rather than waiting for the next scheduled interval.
-c, --cert-check-interval=MINUTES
Resets the interval for checking for new subscription certificates. This value is in minutes. The default is 240, or four hours.
This interval is in effect until the daemon restarts, and then the values in the /etc/rhsm/rhsm.conf file are used (unless the argu-
ment is passed again).
-i, --auto-attach-interval=MINUTES
Resets the interval for checking for and replacing expired subscriptions. This value is in minutes. The default is 1440, or 24
hours. This interval is in effect until the daemon restarts, and then the values in the /etc/rhsm/rhsm.conf file are used (unless
the argument is passed again).
USAGE EXAMPLES
NOTE Be sure to stop the running rhsmcertd daemon before making any configuration changes, or the new configuration is not applied.
RESETTING THE CERTIFICATE SCAN INTERVAL
service rhsmcertd stop
rhsmcertd --cert-check-interval=240
RUNNING CERTIFICATE AND HEALING SCANS IMMEDIATELY
Normally, the certificate and auto-attach scans are run periodically, on a schedule defined in the rhsmcertd configuration. The scans can
be run immediately -- which is useful if an administrator knows that there are new subscriptions available -- and then the scans resume
their schedules.
service rhsmcertd stop
rhsmcertd -n
DEPRECATED USAGE
rhsmcertd used to allow the certificate and auto-attach intervals to be reset simply by passing two integers as arguments.
rhsmcertd certInterval autoattachInterval
For example:
service rhsmcertd stop
rhsmcertd 180 480
This usage is still allowed, but it is deprecated and not recommended.
