19990624: scouring gini


Tom,

the scour script uses the unix "find" command and 1 day is
the smallest increment there.

I use a different script I wrote for Gini, Nexrad and large model
data where I want to keep the last several runs, images etc.

Here is a script that recursively searches through subdirectories
(such as you would use in the nsat/garp configuration) and
keeps the last 20 (defined as KEEP) images.

Store this script in a file called prune_gini.csh.
To use this script, define KEEP as the number of images in each
directory that will be kept. Define "areadir" as the top
level of your gini data (mine has the 1km, 4km, 8km subs underneath,
followed by vis, wv, ir, 3.9 and 12.0 subdirectories etc).
Add the subdirectory where the script will be located to the PATH
definition so that when this script calls itself, it will be found.
Use the chmod command to make the script executable, and your ready to go.
