How to use IDL in a cronjob? [message #87719]

Hello,

I have a bunch of cronjobs that run various tests daily. A shell script
is invoked that does all the heavy lifting, invoking various compiled
executables.

What I would like to do is to add an additional step to my script that
invokes IDL to plot the results of those tests.

I have an IDL batch file that I can invoke at the IDL prompt that
generates the plots.

But how do I invoke that batch file at the OS prompt in a
non-interactive shell process?

Thanks for any info.

cheers,

paulv

In case people are wondering, my word of the day appears to be "invoke". :o\

Not sure if this is what you need, but what I do is use the idl virtual machine (I think !).
You have to locate the file idlrt.exe in you idl distribution and then use it like this (on windows!):
c:\>"c:\Program Files\Exelis\...\idlrt.exe" d:\MySoft\testfile.sav

Of course you need to make a sav file before hand.
Also, I'm not sure how this would look like on linux, but I just guess you need an extra ./ before the executable.

Hope it helps.

Invokingly yours,
Helder

Put the commands you would give at the IDL prompt (like, .run batch.pro) in a file (say, promptcommands.pro). Then you can run it from the shell like this:

$ idl < promptcommands.pro

Sorry, I meant that you can invoke it like that.

Excuse me while I clean up the coffee that squirted out my nose... :o) Ha!

But, back to my question, your suggestion worked. I did

$ idl my_batch_file.pro

and I got all the PNG plots created. Excellent. Thanks.

So simple! I spent about 15 minutes looking through the help and did not
see that described (not saying it's not there, just I couldn't easily
find it).

Effectuatingly Yours,

paulv

Check out the "-e" option at the command line. Can save an intermediate step

Cool! I also notice a "-batch" switch. I'll have to try it. (why can't
*I* find all this useful stuff when I search for it?! Grrr argghh)

My cronjob ran and the IDL plots were produced and squirted onto an ftp
server so invoking IDL sans switches does do the job - but it may rely
on something in my environment. Pudding-proof comes when I move the
whole shebang onto the supa-computers.

Thanks,

paulv
