"Obviously, you're not a golfer". But you are probably a sysadmin.
The cwrap.py script is meant to be used as a wrapper for cron jobs. The idea here is that you use this script to wrap whatever would be a normal cronjob for you to perform functions based on what options are specified. I think this is best explained with an example.
I have a cronjob that runs every minute. First, I don't want "overlap", a second instance is run while the first one is still running, if a single run takes a long time. Solved. The nature of my cronjob (just a script that is being run) is such that there will be an occasional failure, but an occasional failure, in this case, can be ignored. Instead, I only want to know when the script has failed 5 times in a row. Solved. By default, cwrap.py will also swallow all the output for the occasional fails, but I at least want a record of those failures so that I can determine whether the intermittent fails are happening more frequently and constitute a different problem. Solved (by turning on the syslog option).
This script may not be useful for everyone, but for some out there, it will save you a lot of time, effort and probably emails in your inbox.
Just follow the basic install practice for a Python package.
If you have a .tar.gz, extract that first
tar -xvzf cron-wrap*.tar.gz
Now, just cd into the directory and install it
cd cron-wrap* python setup.py install
This should install the script in either /usr/bin or /usr/local/bin depending on your platform. A man page should also be installed.
You can also install this using pip or easy_install
pip install cron-wrap
You have a few options here. Run the script with either "-h" or "--help" to see a list of all the options with a brief description. Otherwise, "man cwrap.py" will give you a bit more info. You can also check the web page at http://stuffivelearned.org/doku.php?id=programming:python:cwrap
