2. snap download hello-world
3. sudo unsquashfs hello-world_27.snap
4. sudo chown -R <user:user> sqaushfs-root/
5. (set -e; for i in {1..258}; do sed -i -e "s/^name: hello-world.*$/name:
hello-world-$i/" squashfs-root/meta/snap.yaml; mksquashfs squashfs-root/
hello-world-$i.snap -noappend -comp xz -all-root -no-xattrs; done )
6. for i in `find . -name \*.snap`;do sudo snap install --dangerous $i; done
7. for i in {1..258}; do hello-world-$i.sh & done
