Re: [Condor-users] Double quotes in a $$([...]) expression

[Mark Calleja <mc321@xxxxxxxxx>]

Hi Mick,

Thanks for the input, but I'm afraid that submitting with that arguments line leads to the job being held, which condor_q -better says is because:

Hold reason: Cannot expand $$([strcat("-singleCompThread -nojvm -r test(1,"" , string(0), ")")]).

I should have said that I'm using version 7.6.9 under Linux.

Regards,
Mark

Hi Mark,

I think you may need to do this:

arguments = "$$([strcat(""-singleCompThread -nojvm -r test(1,"""" , string($(Process)), "")"")])"

The double-quotes at

 

    test(1,"", string ... 

is being submitted as 

    test(1,", string ...

as the two double-quotes imply that you want one of the quotes escaped which I presume is what you don't want to do.


For other reading this, the rules at http://research.cs.wisc.edu/condor/manual/v7.6/condor_submit.html say:


1. The entire string representing the command line arguments is surrounded by double quote marks. This permits the white space characters of spaces and tabs to potentially be embedded within a single argument. Putting the double quote mark within the arguments is accomplished by escaping it with another double quote mark.
2. The white space characters of spaces or tabs delimit arguments.
3. To embed white space characters of spaces or tabs within a single argument, surround the entire argument with single quote marks.
4. To insert a literal single quote mark, escape it within an argument already delimited by single quote marks by adding another single quote mark.

Regards.
