<p>Hi Evgeny,</p>
<p>One way to do it is to add this as an arg to your grads script.
For example,</p>
<p>function get_gfs(args)<br>
datenow = subwrd ( args, 1 )<br>
'sdfopen
<a class="moz-txt-link-freetext" href="https://nomads.ncep.noaa.gov/dods/gfs_0p25/gfs'datenow'/gfs_0p25_12z">https://nomads.ncep.noaa.gov/dods/gfs_0p25/gfs'datenow'/gfs_0p25_12z</a>'</p>
<p>Then when you run the script,</p>
set datenow = `date +%Y%m%d`<br>
grads -lcb "run my_script.gs datenow"
