Linux find what processes are swapping

Here is a handy script that will check all processes and report what is swapping

#!/bin/bash
for pid in `ps x|awk '{print $1}'`; do
result=`cat /proc/$pid/status|grep VmSwap|awk '{print $2}'|grep -v ^"0"`
if [ ! -z "$result" ]; then
 programresult=`ps x|grep $pid|grep -v grep`
 if [ $? == 0 ]; then
     program=`echo $programresult|awk '{print $5}'|grep -v ^grep`
 fi
 echo "$pid $program swap = $result kB"


fi
done

You can also pipe the output like this to sort the largest swap processes:

|sort -nr -k4

 

The old way that never worked very well:

 

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  SWAP COMMAND      
 7371 on       20   0 1558m 1148  740 S    0  0.0   0:00.02 1.5g services.exe 
 7369 on       20   0 1558m 1084  708 S    0  0.0   0:00.02 1.5g wineboot.exe

Run top then press 'O' (capital letter o) followed by 'p' then 'enter'. Now processes should be sorted by their swap usage.
