[gradsusr] "No Files Open" When Running In Batch Mode

[Perry, Aaron @ LSC]

Hi Jim,

I tried the changes that you suggested and unfortunately I still have the same problem. I also tried just entering the actual date instead of trying to set a command to create the current date, didn't work.

Adding the " " around !date +%Y%m%d seemed to help and so did doing just one ">" but, when I tried changing >> to >!, I kept getting this error message "date: extra operand `/home/muaddib/grads/date/date.formatted' Try `date --help` for more information" and then it goes back to the usual "No Files Open No files open" message.

Could you elaborate a little bit more about the .bashrc approach? In my bash script, I'm defining the date variable as "YMD=`date +%Y%m%d` to pull .grib2 data via wget and then convert it through g2ctl and gribmap. I wouldn't think that would affect GrADS, right?

Here's the part in the bash script where I'm running GrADS:

GRADS=/usr/local/lib/grads/./grads
PATH3=/grads/scripts/gem/25km/12/
FHR0=000
HOMEDIR=/home/muaddib

${GRADS} -clb "run ${HOMEDIR}${PATH3}500GPH_${FHR0}.gs"

Aaron:

I think the problem is with the "date" command.  You can test this with
specifying the date (replace the top lines with a constant date).  If this
is indeed the case, some suggestions:

1.  Try with double quotes around the arguments to date, e.g.,

'!date +"%Y%m%d" >> /home/muaddib/grads/date/date.formatted'

I think you want a date like 20131226, but with single quotes around
the argument I think you'll get something like "Ymd".

2.  Is it possible you have two different "date" commands?  It could
be running in batch mode is using a different path that when you are
running interactively (e.g., you have a .bashrc or .cshrc that is not
accessed in batch mode).

3.  The >> syntax will append the output to file date.formatted,
but your script is always accessing the second line of this file:
sysdate = sublin(d,2)
Not sure why you have this.  Have you tried >! to overwrite the
file, then read the first line?

You've probably got a 'q time' command in your script before you open any files, or after you open a file with some error. But without knowing what script you're running on startup, it's impossible to help any further.

Good Morning All,

Currently, I'm having an issue where "No Files Open" pops up every time that I run GrADS in Batch Mode (grads -clb).

This results in the Valid Forecast Time not being displayed on my plots. At first, I thought that it was an issue of the 'set t 1' placement after 'reinit', as I'm using g2ctl/gribmap ctl files.

I've sort of narrowed this down to just a batch mode problem because, when I open the .gs file with 'grads -l' , "No Files Open" does not pop up and the Valid Forecast Time shows up on the plot.

Has anybody else had this issue before?
