Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

Paging? Swapping? Which is it?

It's a bit big to be called a "one-liner", but this "script" will give you a short overview of paging levels vs. swapping levels on your machine.

Set T=<seconds> to whatever timeframe you want to test for.

T=5; ( vmstat -s; sleep $T; vmstat -s ) | awk -v T="$T" -F'[(/)]' '/pages paged in/{ pgpio=pgpin; pgpin=$1 } /pages paged out/{ pgpoo=pgpon; pgpon=$1 } /pages swapped in/{ pgsio=pgsin; pgsin=$1 } /pages swapped out/{ pgsoo=pgson;
