You must first tell your bash what g2ctl is and where it is located.<br>
<br>
Open up a new terminal and type "gedit .bashrc"<br>
<br>
>From there, set an alias for g2ctl (including the absolute path to where it's located in your filesystem)<br>
<br>
Then exit out of the terminal and try running g2ctl again and see if it works.<br>

<div>Hey Eric,</div>
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.
<div>Thanks,</div>
<div>Ethan<br>

Hi Ethan,
<div><br>
</div>
<div>The g2ctl is a perl script, not a grads command. You have to run it from the shell command line, not inside grads.</div>

Hi Aaron,<br>
I am attempting to carry out this process by typing in 'g2ctl gfs_4_20140112_1200_009.grb2 > gfs_4_20140112_1200_009.ctl'. I got an error saying 'unknown command: g2ctl'. Any thoughts on this? Thanks so much.<br>
<br>
Ethan<br>
