One command I miss from my old Unix days is the ability to add swap dynamically. That is swap to a file. Some of the Unix's have a swap command and you can name a file and the size you wish and swap will start using it. This can be pretty handy for someone who doubles their RAM after and OS has been installed and wants swap to follow the yellow brick road even if the machine never swaps. I did a man on swap but nothing came back!

Thank you, that was just what I wanted and quite helpful.

Try 'man -k' or 'apropos' next time $ man -k swap mkswap (8) - set up a Linux swap area swapon (2) - start/stop swapping to file/device swapoff (2) - start/stop swapping to file/device Theo -- Theo v.

IIRC, you can create a swap file and add it.
