## Shell scripting

```{r, engine='bash', eval=FALSE}
#!/bin/bash
cd ../data
fnin="ndvi.tif"
fnout="ndvi_latlong_60.tif"
fntemp="temp.tif"
fnpng="ndvilatlong.png"
echo "resample the inputfile: $fnin"
gdalwarp -tr 60 60 -r cubic $fnin $fntemp
echo "reproject to lat/long: $fnout"
gdalwarp -t_srs EPSG:4326 $fntemp $fnout
rm $fntemp
gdal_translate -of png $fnout $fnpng
echo "The output file: $fnout"
```
