Read from file in Edit Configurations

In order to make use of the in built CLions run/debugging tools I am passing command line arguments to my executable as a space separated vector input to the 'Program arguments:' option of the 'Run -> Run/Debug Configurations' window.

I would like to be able to read this vector of arguments directly from a file, rather than inputting them manually i.e. edit/save external file pars_template.csv then pass the following to Program arguments:

`$(sed -n '2p' ../Params/pars_template.csv)`

This doesn't work!

Any ideas on how I could run a program _through CLion_ accessing external program arguments?

Thanks!
