Which processes are using your swap ? (Linux)

Here is a simple bash script which briefly shows you the processes using your Linux's swap area.

#!/bin/bash

exec 2>/dev/null
total=0
printf "pid\t\tprocess\t\tmemory (kB)\n"
while read -r me
do
 ps=$(cat $me/comm)
 res1=$?
 val=($(grep "^VmSwap" $me/status))
 res2=$?
 p=$(basename $me)
 if [[ $res1 -eq 0 && $res2 -eq 0 ]]; then
  if [ ${val[1]} -ne 0 ]; then
   printf "%d\t\t%s\t\t%s\n" "$p" "$ps" "${val[1]}"
   let total=$total+${val[1]}

  fi
 fi
done < <(find /proc/ -mindepth 1 -maxdepth 1 -type d -name "[0-9]*" )
echo "Total(kB):$total"

Sample output (processes not sorted by their memory usage)
