[gradsusr] Opening a Grb2 File

[Ethan Sacoransky]

Hey Eric,
Unfortunately, this command is still not working in a basic terminal shell. Here is what I put through: 'g2ctl grib2_gfs_4_20140112_1200_009.grb2 > grib2_gfs_4_20140112_1200_009.ctl' and this is the error I am getting: '-bash: g2ctl: command not found'. Any thoughts on this would be much appreciated.
Thanks,
Ethan

When I type in the command 'run g2ctl gfs_4_20140112_1200_009.grb2' I get the prompt, "error opening script file: g2ctl".  Any thoughts on why this would be?
