Check the total memory usage of processes with a specific name

pids=$(pidof chrome); for p in ${pids[@]}; do cat /proc/$p/status | grep -i vmrss | awk '{print $2}'; done | while read m; do let t=$t+$m; echo $t; done | echo "$(tail -n 1) kB"
Get the total RESIDENT memory used by processes of a specific name. This means this is the MINIMUM used by a process, but some memory could be paged out to swap.
Sample Output
$ pids=$(pidof chrome); for p in ${pids[@]}; do cat /proc/$p/status | grep -i vmrss | awk '{print $2}'; done | while read m; do let t=$t+$m; echo $t; done | echo "$(tail -n 1) kB"
