[gradsusr] Gribmap

[Goodson,Ron [Edm]]

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?
