Hi i am trying to find the solution for find users cpu and mem unable to find it. as per the command it is unable to sort by cpu. ps ww -e --sort -rss o user,pid,pmem,command,rss,size,vsz|head -20 this will sort by user it will show nobody user ps ww -e --sort -rss o cpu,pid,pmem,command,rss,size,vsz|head -20 this will not sort by cpu. If i know the user name for example abc.com is domain name using abc is username if i would like to find only how much cpu and mem is used for abc how to find? ps will not help ps -u nobody no use i think following command will help i dont know how to use top -hv | -bcisS -d delay -n iterations [-u nobody | -U nobody] -p pid [,pid] Thank you, Kaushal
