Re: [Condor-users] Looping in Condor job description scripts?

[Wei Wang <ww@xxxxxxxxxxxx>]

Hi, 

Thanks to everyone's help. I actually just got a chance to try the fancy way, $$([ClassAd Expr]), suggested by Alan and Dan. However, I got no luck. The whole thing, i.e. $$([*]), is treated literally but not get evaluated. Is there anything that I'm missing?

Here is the script I use:

log = $$([$(Process)+100]).log

But I get a log file called like:

$$([7+100]).log

Well, 7 is correctly replaced but not the _expression_. Same story for Dan's suggestion using the String approach. What did I do wrongly? Thanks!

Hi Wei,

Yes, Condor 7.2.2 is recent enough to use the $$([ ... ]) ClassAd
_expression_ syntax in the way that was suggested.

Here's one way to get 6-digit numbers of equal length with leading zeros:

Arguments =
"$$([substr(strcat(string(0),string(0),string(0),string(0),string(0),string(0),string($(Process))),-6)])"

This produces the sequence

000000
000001
000002
...

To my surprise, the following somewhat simpler _expression_ did not work:

Arguments = "$$([substr(strcat(""000000"",string($(Process))),-6)])"

It seems that double quotes are not correctly handled inside of $$([ ...
]) expressions.
