Functions

func CPUTop

func CPUTop() error

CPUTop will list all the process in a tabular form

func GetPids

func GetPids() (pids []string, err error)

GetPids returns a slice of IDs for all of the currently running processes

func GetProcessTree

func GetProcessTree() gotree.Tree

GetProcessTree returns a tree with process ancestral hierarchy

func ListProcess

func ListProcess() error

ListProcess will list all the process in a tabular form

func MemTop

func MemTop() error

MemTop will list all the process in a tabular form

func OrderedBy

func OrderedBy(less ...lessFunc) *multiSorter

OrderedBy returns a Sorter that sorts using the less functions, in order. Call its Sort method to sort the data.

func PrintProcessTree

func PrintProcessTree()

PrintProcessTree prints a tree of processes with their ancestral hierarchy

func Top

func Top(ps []*Process, res string) error

Top will return top result for RAM and CPU
