[MITgcm-devel] testreport on my mac

[Martin Losch]

Hi again,

I seem to be bored so here’s my suggestion (after testing a lot of different stuff):

	      adm_diva_nb=`sed -n '/^ *add_DIVA_runs *=/p' run_ADM_DIVA | sed 's/ //g'`

This will catch the space “ “ (or no space) before the “=“ sign. One could also do “^ *add_DIVA_runs.*=“, then it would find also things like "add_DIVA_runsxxx =“. I am not sure why this is so complicated anyway. Do we plan to have many variants of run_ADV_DIVA, anyway?

If no-one has a better idea, I’ll create PR soon.

Martin
