I have a Python script that I would like to run on sun grid engine, and this script accepts a string command line argument that might contain braces. For instance, the script could be script.py:
import sys
print(sys.argv[1])
If I run python script.py aaa{ the output is aaa{, and if I run python script.py aaa{} the output is aaa{}. These are both the desired behavior.
However, if I run qsub -b y -cwd python script.py aaa{ the job fails with error Missing }., and if I run qsub -b y -cwd python script.py aaa{} the job succeeds but outputs aaa. This is not the desired behavior.
My hypothesis is that qsub does some preprocessing of the command line arguments to my script, but I don't want it to do this. Is there any way to make qsub pass command line arguments to my script as is, regardless of whether they contain braces or not?
I was able to solve my problem by running qsub -b y -cwd -shell no python script.py aaa{} instead of qsub -b y -cwd python script.py aaa{}. On my system, -shell yes seemed to be enabled by default, which initiated some preprocessing. Adding -shell no appears to fix this.
