Commands tagged memory usage from sorted by
Terminal - Commands tagged memory usage - 11 results
ps -eo pmem,comm | grep application-name
2014-02-23 13:21:29
User: Darkstar
Functions: grep ps
0

Displays memory usage for individual instances of an application that spawns multiple instances of itself. This command also works on single process applications.

CMD=chrome ; ps h -o pmem -C $CMD | awk '{sum+=$1} END {print sum}'
watch -n 10 free -m
2014-01-04 10:10:15
User: Darkstar
Functions: free watch
-1

This command shows a high level overview of system memory and usage refreshed in seconds. Change -n 10 to you desired refresh interval.

ps -eo pmem,comm | grep chrome | cut -d " " -f 2 | paste -sd+ | bc
2014-01-03 15:33:16
User: Darkstar
Functions: cut grep paste ps
0

This command will show the sum total of memory used in gigabytes by a program that spawns multiple instances of itself. Replace chrome with whatever program's memory usage you are investigating. This command is rather useless on software that only spawns a single instance of itself.

ps -u marcanuy -o pid,rss,command | awk '{print $0}{sum+=$2} END {print "Total", sum/1024, "MB"}'
2013-11-20 01:21:59
User: marcanuy
Functions: awk ps
0

Add up the amount of memory your processes are using and display the total. Replace marcanuy with your desired username.

smem is very clever, it keeps in mind shared memory in its calculations!!!

ps -eo size,pid,user,command --sort -size |awk '{hr[1024**2]="GB";hr[1024]="MB";for (x=1024**3; x>=1024; x/=1024){if ($1>=x){printf ("%-6.2f %s ", $1/x, hr[x]);break}}}{printf ("%-6s %-10s ", $2, $3)}{for (x=4;x<=NF;x++){printf ("%s ",$x)} print ("\n")}'
TOTAL_RAM=`free | head -n 2 | tail -n 1 | awk '{ print $2 }'`; PROC_RSS=`ps axo rss,comm | grep [h]ttpd | awk '{ TOTAL += $1 } END { print TOTAL }'`; PROC_PCT=`echo "scale=4; ( $PROC_RSS/$TOTAL_RAM ) * 100" | bc`; echo "RAM Used by HTTP: $PROC_PCT%"
sudo ps aux --sort:rss | awk '{print $2"\t"$11": "$6/1024" MB"}' | column -t | less
command ps wwo pid,user,group,vsize:8,size:8,sz:6,rss:6,pmem:7,pcpu:7,time:7,wchan,sched=,stat,flags,comm,args k -vsz -A|sed -u '/^ *PID/d;10q'

I've wanted this for a long time, finally just sat down and came up with it. This shows you the sorted output of ps in a pretty format perfect for cron or startup scripts. You can sort by changing the k -vsz to k -pmem for example to sort by memory instead.

If you want a function, here's one from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

aa_top_ps(){ local T N=${1:-10};T=${2:-vsz}; ps wwo pid,user,group,vsize:8,size:8,sz:6,rss:6,pmem:7,pcpu:7,time:7,wchan,sched=,stat,flags,comm,args k -${T} -A|sed -u "/^ *PID/d;${N}q"; }
pmap $(pgrep [ProcessName] -n) | gawk '/total/ { a=strtonum($2); b=int(a/1024); printf b};'
