One example of using a flag, or lock file.
A good place to put such a file is the /tmp directory. The cleanup function should ensure that the file is deleted on exit, so you don't have to remember to put
everywhere you exit the program. Putting the PID in the file and then checking whether the process exists is optional, and there in case the program exits abnormally, leaving the file in place.
Hey guys,
I'm writing a monitoring program that reads the pattern and the max and min number of instances of a process and then proceeds to parse the currently running processes for the pattern.

Hi,
I need to establish a procedure that will start an application in background each time my remote Solaris server is (re)started. This would be a kind of daemon. I am no sysadmin expert, so I am looking for pointers.
How should I proceed? What are the main steps?
Thanks,

yum-cron
yum-cron(8)yum-cron(8)NAME
yum-cron - an interface to convieniently call yum from cron
SYNOPSIS
yum-cron [config-file]
DESCRIPTION
yum-cron is an alternate interface to yum that is optimised to be convenient to call from cron. It provides methods to keep repository
metadata up to date, and to check for, download, and apply updates. Rather than accepting many different command line arguments, the dif-
ferent functions of yum-cron can be accessed through config files.
config-file is used to optionally specify the path to the configuration file to use. If it is not given, the default configuration file
will be used. It is useful to be able to specify different configuration files for different use cases. For example, one configuration
file might be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file.
Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day.
FILES
/etc/yum/yum-cron.conf
/etc/yum/yum-cron-hourly.conf
SEE ALSO

BUGS
There of course aren't any bugs, but if you find any, you should email
the mailing list, yum@lists.baseurl.org, or consult bugzilla.
