Another approach... Move all the 'environmental' depend dependencies from being 'hard-wired' in the script itself into a separate configuration script which gets "sources" by the 'main' script.
One of the settings in the config file could be:
Code:
# dev test prod
ENVIRON='dev'
You could reference the var ENVIRON in your main script and make needed choices without changing the script itself.
just my $.02
We have a configuration script - and we have used the type of approach you are talking about. However, that means that the environmental scripts are not IDENTICAL between the regions, which is something you want to prevent things being added and removed are done for each region. We also use PVCS for promoting, and each script should work as is, untouched, in each region.

I agree! However, we have not found a good alternative to this one.

Use one myservice.conf in development, ship another to install it somewhere else.
Email: Depends on how your script handles that. It may be possible to leave it up to the server where email goes.
For that matter: Why are the settings so different in your development server than your deployment ones?
To answer your last question first - at one time we had our DEV and QA regions on the same box. Therefore we could not have (ex) /app/scripts represent our scripts directory for both DEV and QA. So, we came up with /app/test/scripts for dev, and /app/prod/scripts for BOTH QA and Production. The theory is that QA should look exactly as production does, hence the same directory names.
Other things also create a need to handling things differently between regions, such as dealing with different DSNs on the MVS we have to communicate and send files to. Their dev region names are TEST.D, QA is TEST.X, prod is PCS.P. Our environmental script that determines what region we are running in, sets variables to build the correct DSN on the MVS, which may be participating in the test. The email thing - that's a safety feature. If a developer (and that's who we are - developers trying to figure this best practice) is working on a project, pressed for time, and everyone's hollering about getting the test emails, he can tell the script that when in DEV, send them to his email. Then if he forgets to change that back to the group email - the script handles it by saying "When I'm running in prod, send the email to the group".
Your first suggestion - sanity checks on directory names. If the directories are identical between QA and PROD, then directory checks to determine differences in the regions would not be able to tell the difference.
Hi:
Let's suppose I want to replace all the | by > ONLY when | is between . Usually (and it works) I would do something like
sed -e 's/\(\*\)|\(*\]\)/\1>\2/g'
where I have to "save" some portions of the matched region and use them with the \n metacharacter. I was wondering if I could... (2 Replies)
Hi guys,
I hope everybody is doing fine. I have written this small program which solves the critical region problem. Only on of the two threads can make changes to a common variable called counter. I am using two semaphores, is it possible to write the same program using only one semaphore? Here... (0 Replies)
