top,ps查看进程使用内存情况
ps -e -o 'pid,comm,args,pcpu,vsz,stime,user,uid' |grep chrome|grep -v grep
watch 'ps -e -o 'pid,comm,args,pcpu,rsz,vsz,stime,user,uid' |grep chrome |grep -v grep'
ps -aux|awk '{print $4"\t"$11}'|grep -v MEM|sort -r
ps -axu|awk '{print $4,$11}'|sort -r
top -b -n 1 |grep chrome|awk '{print "cpu:"$9"%","mem:"$10"%"}'
top -d 1
然后shift + m（Sort by memory usage）
