[gradsusr] Gribmap

[Goodson,Ron [Edm]]

p.s. --> and sometimes its a permission problem that when run from cron,
there is no permission to write to the directory you are using.
 
eithe way, I sure its something you will solve - and wil be obvious once
you know the answer.

I saw the earlier note about changing directory to the file with the
data.  That might be required if your ctl file has a relative path to
the data instead of absolute
 
dset ^myfile.
 
Sometimes these problems are because some environment variable is not
set properly when the job is executed by cron.
 
The easieset thing to do to find out the error is in the cron file, set
the output for stdout and stderr to a logfile, so you can see what error
message is thrown.
 
/bin/myfile  1>log.txt  2>&1
 
1 > log.txt        means send stdout to the file log.txt
2>&1               means send stderr (error messages) to the same file
as stdout.

I'm new to Linux and I'm pulling my hair out trying to figure out why
gribmap will not run when executed as a cron job.

 

In crontab I execute a .sh script that has something that looks like:

 

#!/bin/bash

 

/wrf/wrfems/util/grads/bin/grib2ctl.pl -verf
/wrf/wrfems/runs/float/emsprd/grib/arw_0000.grib >
/wrf/wrfems/runs/float/emsprd/grib/arw_0000.ctl

 

/wrf/wrfems/util/grads/bin/gribmap -I
/wrf/wrfems/runs/float/emsprd/grib/arw_0000.ctl

 

 

 

The last line is the problem child. Note that the script is running, and
the first line in the script (converting GRIB to a CTL file) works, but
nothing happens when trying to execute the gribmap executable.

 

Also I should note that if I type that same line in the terminal it DOES
work, just not in crontab.

 

Any ideas?
