[Condor-users] config settings using output of command

[Dan Christensen <jdc@xxxxxx>]

Is it possible to do something like

CONFIG_SETTING = $SHELL(whoami)

to set a configuration variable to the output of a command?  The
motivating example would be something like

HASPYTHON = $SHELL(which python > /dev/null && echo True || echo False)
STARTD_EXPRS = HASPYTHON, $(STARTD_EXPRS)

so that machine classAd's indicate whether they have a certain
executable installed.

Or is there another way to achieve this?

Thanks,

Dan
