这是官网脚本,搞不懂这些| cut -f2 -d'=' | cut -f1 -d','" 都是什么意思:
; Script display location of model domains
; Only works for ARW domains
; Reads namelist file directly
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"

end而且运行的时候提示找不到namelist.wps文件,我已经确认了文件路径的
