  • Display the top processes sorted by memory usage. This is mostly useful because it's easy to remember and can give me a quick 'top' view of a group of servers when used over pssh. (Though I'd recommend |head -10 to minimize the output). Show Sample Output

    top -b -o +%MEM |head -17

  • This command is better for just displaying the memory in KiB. Show Sample Output
