Splitting shapefile into separate files within Meridians using QGIS

Given a .shp that covers the globe, how could QGIS be used to segment that into 90 .shp files, each file containing lines/points/polygons/multipolygons that are between the first and second then second and third then third and fourth, etc?

Issue is a series of gigantic source files with global coverage that have no common attributes that would allow them to be conventionally partitioned. Since the source files have a relatively even distribution (not over the Pacific ocean of course), cutting them up into smaller files will make them cleaner to process.

I was hoping there was a hidden command in ogr2ogr that would do this, but I don’t see one.

for x in `seq -180 10 170`; do
     x2=$((x+10))
     ogr2ogr -spat $x -90 $x2 90 -spat_srs epsg:4326 outfile_$x.json infile.shp
done
