[ncl-talk] Question concerning listing files

[Barry Lynn]

Dennis, thank you.

Here is the sequence of calls to produce the list, for reference of list
users.

begin
; http://www.ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml
; to retrieve a list of files from another directory
 Date = "20130208/"
 DATADir = "/data1/wrf/NAM/"
 diri = DATADir+Date
 all_files = systemfunc("ls " + diri + "nam*grb") ; notice quotes around ls
as well.
 n_files = dimsizes(all_files)
 print("n_files = " + n_files)
 do n=0,n_files -1
   print("all_files(n) = " + all_files(n))
  filename = all_files(n)
  print ("filename" + filename)
  a = addfile(filename,"r")
  nc_file = a
  MY_PRES = nc_file->PRMSL_218_MSL
  print("MY_PRES" + MY_PRES(5,5))
  end do
end
