I have several nc files share the same name partially (like *CNRM*.nc). I want to read them all in once. So I used SPAWN:"ls *CNRM*.nc". However, the returns contain double quotation marks like "pr_Amon_CNRM-AM6-DIA-v2_LandControl_r1i1p1_196901-200812.nc" which fails to make use data_file work because it's actually use "data_file". Any suggestions?
