So this will be a very short article, but it is something I find very useful from time-to-time, especially when compiling code on a cheap cloud server with very limited resources. Here’s how to enable a temporary swap file without having to have a partition dedicated to it:

1 sudo dd if=/dev/zero of=/swap bs=1M count=2048
2 sudo mkswap /swap
3 sudo swapon /swap

And that’s it! Just change the 2048 in count=2048 to however many kilobytes you’d like the swap file to be.
