Dear jobsub experts,

I have a script which takes a whole command (with its own arguments) as one parameter. It works, however, when I am running the script through jobsub_submit, " are eaten and my whole command is split and its parameters are treated as the main script parameter.

Lets say I have a script: runCommand.sh which can take a string as a parameter (my command to run), e.g.

runCommand.sh -a arg1 -b arg2 -c "myCommand -a arg3 -b arg4"

When I pass this to jobsub_submit, e.g.

jobsub_submit -G genie -M --OS=SL6 --resource-provides=usage_model=DEDICATED,OPPORTUNISTIC file://runCommand.sh -a arg1 -b arg2 -c "myCommand -a arg3 -b arg4"

then jobsub understand this like:

runCommand.sh -a arg1 -b arg2 -c myCommand -a arg3 -b arg4

so arg3 and arg4 are treated as runCommand.sh arguments. I tried escape \", but it did not help.

Is there a way to make this work?

Thanks,
Tomek

p.s. I sent this email to (I found the email address here: https://cdcvs.fnal.gov/redmine/projects/fife/wiki/Submitting_jobs_via_jobsub), but apparently it does not really work?

Hello jobsub experts,

We also encounter this issue in the NOvA group. A quick look at the jobsub indicates that the problem is connected with the way the wrapper script is constructed -- pylib/groupsettings/JobSettings.py lines 569-570 show that script options are being constructed as a string, so any difference between opts = [ "opt 1" ] and opts = [ "opt", "1" ] is lost when converted into a string opts = "opt 1".

There is however a simple(but not fully correct) workaround -- when constructing script_args(pylib/groupsettings/JobSettings.py, lines 569-570) we can surround separate arguments by single(double) quotes, which will help bash to determine how to correctly parse arguments. I.e. we can replace

for x in settings['script_args']:
script_args = script_args+x+' '

by

for x in settings['script_args']:
script_args += "'" + x + "' "

or we may also safeguard and escape single quotes in the x, like:

for x in settings['script_args']:
script_args += "'" + x.replace("'", "'\\''") + "' "

Thank you,
Dmitrii
