==== Somme la RAM de tous les processus associés d'un programme. ====<br />
<syntaxhighlight lang="bash" line copy><br />
ps aux | grep chrome | awk '{print $4, $6/1024 " MB"}'<br />
</syntaxhighlight><br />

</syntaxhighlight><br />
<br />
==== Comment obtenir une mesure fiable ? ====<br />
Option 1 : Utiliser smem (recommandé)<br />
<syntaxhighlight lang="bash" line copy><br />
sudo smem -c "name pss rss" -P chrome | awk '{pss+=$2; rss+=$3} END {print "PSS:", pss/1024, "Mo | RSS:", rss/1024, "Mo"}'<br />
</syntaxhighlight><br />
PSS : Mémoire partagée répartie équitablement (plus précis).<br /><br />
RSS : Mémoire totale (comme ps).<br /><br />
<br />
==== Rapport détaillé PSS/RSS pour Chrome. ====<br />
<syntaxhighlight lang="bash" line copy><br />
sudo smem -t -k -P chrome<br />
