Easy way to add subscribers to hss without node.js / web UI

Hi Sukchan and list,

I was wondering if there was a way to create subscribers in the HSS from a script or from the command line and avoid/bypass all the node.js and npm "nightmare" (I know, it's a matter of taste, but to me it is). Particularly for automated tests, I wouldnt't want to write scripts against a web gui to create subscribers.

Also, for most operators (small or big), I guess they want to import a bulk CSV (or other format) file with key data. If there was a way to add subscribers from a script / command line, I could e.g. writea script to import the CSV for the sysmoUSIM/SJS1 easily.

Thanks for any assistance.
