[ncl-talk] ncl systemfunc

[Matthias Demuzere]

Hi Rick,

Yes... I tested this for a single string without curly brackets (eg. *.nc) and that works fine ...
Does this indicate there is somehow a system dependency, even though the curly brackets do work directly in the terminal? Quite puzzling, no?

Hi Matthias,

That is very odd -- it works for me, both at bash command line and using systemfunc() from within NCL.  Can you get systemfunc to return files from a directory without using "{}" notation, .i.e, "ls *" for example? Or simply "ls foo" where the file foo is known to exist in the current directory?

Dear all,

I am currently testing the CVDP (http://www.cesm.ucar.edu/working_groups/CVC/cvdp/) which is written in ncl.
Currently the software does not run because it can't find the proper datasets.

Finding the data is driven by the systemfunc command using curly brackets (multiple options).
For example, within ncl, I want to list all files that have one of the following extension: .nc, .hdf, .pdf.

This I do with:
myFiles = systemfunc("ls /DIRECTORY/*{.nc,.hdf,.pdf}")

If I fo this in ncl, I get an error: ls: cannot access '/DIRECTORY/*{.nc,.hdf,.pdf}': No such file or directory

Yet, when pasting ls /DIRECTORY/*{.nc,.hdf,.pdf} directly in my system (ubuntu 16.04, 64bit) terminal, I do get a list of the finals with this extension. So the expected result.

I have tested this in ncl-6.3.0 and 6.2.1, but I have the same problem in both.
Did anyone else notice this before? Any idea on how to fix this?

Thanks!

Regards,
Matthias
