  • Display the top ten running processes - sorted by memory usage

    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


    0
    top -b -o +%MEM |head -17

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4962, cleaned up, shortened, and more efficient. Now a ' * ' can be used as the box character, and the variables get unset so they don't mess with anything else you might have. They marked c++ as a function for this command, but I'm not sure why. Must be a bug.
