Hi Aaron:<br>
<br>
Just to be clear, in your script the line '!date +.....' will create
a single line file with the date as the single line, e.g.,
20131226. Then, the third line in<br>
your script is sysdate = sublin(d,2) which is trying to read the
second line of the file created (which I think should only have one
line). So, you should <br>
change this third line (I think) to:<br>
<br>
sysdate = sublin(d,1)<br>
<br>
Next, you have an issue with the "date" command redirect. On most
operating systems a ">>" (double) will append to an existing
file, and a <br>
">!" will overwrite the file. The single ">" is different on
different systems, on some it overwrites and on others it appends.
So, ideally I think<br>
you want a ">!" since a ">>" will append to a file, but you
are always reading the same line (hope that makes sense). Finally,
at least on my<br>
system the grads script is reading the single quote in the date
command as a termination of the command. So, I think what you
really want is:<br>
<br>
'!date +"%Y%m%d" >! /home/muaddib/grads/date/date.formatted'<br>
d = read('/home/muaddib/grads/date/date.formatted')<br>
sysdate = sublin(d,1)<br>
<br>
However, the ! part of >! is apparently not allowed in the Grads
script (I think the ! means to escape from grads for a system
command). So,<br>
if you can confirm that a single ">" will overwrite a file, and
change the sublin(d,2) to sublin(d,1) you are probably ok:<br>
<br>
'!date +'%Y%m%d' > /home/muaddib/grads/date/date.formatted'<br>
d = read('/home/muaddib/grads/date/date.formatted')<br>
sysdate = sublin(d,1)<br>

<br>
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.<br>
<br>
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.<br>
<br>
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?<br>
<br>
Here's the part in the bash script where I'm running GrADS:<br>
<br>
<b>GRADS=/usr/local/lib/grads/./grads<br>
PATH3=/grads/scripts/gem/25km/12/<br>
FHR0=000<br>
HOMEDIR=/home/muaddib<br>

I think the problem is with the "date" command. You can
test this with<br>
specifying the date (replace the top lines with a constant
date). If this<br>
is indeed the case, some suggestions:<br>
<br>
1. Try with double quotes around the arguments to date,
e.g.,<br>
<br>
'!date +"%Y%m%d" >>
/home/muaddib/grads/date/date.formatted'<br>
<br>
I think you want a date like 20131226, but with single
quotes around<br>
the argument I think you'll get something like "Ymd".<br>
<br>
2. Is it possible you have two different "date" commands?
It could<br>
be running in batch mode is using a different path that when
you are<br>
running interactively (e.g., you have a .bashrc or .cshrc
that is not<br>
accessed in batch mode).<br>
<br>
3. The >> syntax will append the output to file
date.formatted,<br>
but your script is always accessing the second line of this
file:<br>
sysdate = sublin(d,2)<br>
Not sure why you have this. Have you tried >! to
overwrite the<br>
file, then read the first line?<br>
<br>

<div>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,<br>
<br>
Currently, I'm having an issue where
"No Files Open" pops up every time
that I run GrADS in Batch Mode (grads
-clb).<span
class="Apple-converted-space"> </span><br>
<br>
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.<br>
<br>
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.<br>
<br>
Has anybody else had this issue
before?<br>
