Alright, sublin actually returns two lines, a return code (line 1)
and the value (line 2), so "sublin(d,1)" is incorrect. Can you try
this:<br>
<br>
'!date +"%Y%m%d" > date.formatted'<br>
d = read('date.formatted')<br>
sysdate = sublin(d,2)<br>
'draw string 4.0 4.0 'sysdate<br>
<br>
If you save this to a script and run it, you should get the date as
a string right in the center of the GrADS display window. If this<br>
works we can at least eliminate the "date" and re-direct issues.<br>

<br>
I really appreciate all the assistance with this date issue. <br>
<br>
Unfortunately, using sublin(d,1) absolutely refuses to work
for me so, I think I'm just going to try setting the date
outside of GrADS before I run my script:<br>
<br>
Ex:<b><br>
<br>
<u>In bash script:</u><br>
</b><br>
YMD=`date +%Y%m%d`<br>
<br>
grads -clb "run ${HOMEDIR}${PATH3}500gph_${FHR0}.gs ${YMD}<br>
<u><b><br>
In GrADS .gs script:</b></u><br>
<br>
function pull (args)<br>
<br>
currdate = subwrd(args,1)<br>
<br>
<br>
Believe it or not, I'm still having an issue where "No Files
Open" still popping up when GrADS is run and the valid
forecast hour not showing up on my plots. I've attached a
sample of what's happening to this email and an updated
version of the script. I feel like the issue is with fdate and
fday from 'q time' but, from what I can tell the coding checks
out.<br>
<br>
This is becoming quite frustrating...<br>

<div>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>

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>

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>

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

<br>
This results in the Valid

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

the plot.<br>
