func BootTimeWithContext(ctx context.Context) (uint64, error)
func ByteToString(orig []byte) string
func CallLsofWithContext(ctx context.Context, invoke Invoker, pid int32, args ...string) ([]string, error)
func CallPgrepWithContext(ctx context.Context, invoke Invoker, pid int32) ([]int32, error)
func DoSysctrl(mib string) ([]string, error)
func GetEnv(key string, dfault string, combineWith ...string) string
GetEnv retrieves the environment variable key. If it does not exist it returns the default.
func GetOSRelease() (platform string, version string, err error)
func HexToUint32(hex string) uint32
HexToUint32 parses Hex to uint32 without error.
func HostDev(combineWith ...string) string
func HostEtc(combineWith ...string) string
func HostProc(combineWith ...string) string
func HostRun(combineWith ...string) string
func HostSys(combineWith ...string) string
func HostVar(combineWith ...string) string
func IntContains(target []int, src int) bool
IntContains checks the src in any int of the target int slice.
func IntToString(orig []int8) string
func MockEnv(key string, value string) func()
MockEnv set environment variable and return revert function. MockEnv should be used testing only.
func NumProcs() (uint64, error)
func PathExists(filename string) bool
func Read(r io.Reader, order ByteOrder, data interface{}) error
Read reads structured binary data from r into data. Data must be a pointer to a fixed-size value or a slice of fixed-size values. Bytes read from r are decoded using the specified byte order and written to successive fields of the data. When reading into structs, the field data for fields with blank (_) field names is skipped; i.e., blank field names may be used for padding. When reading into a struct, all non-blank fields must be exported.
func ReadFile(filename string) (string, error)
ReadFile reads contents from a file.
func ReadInts(filename string) ([]int64, error)
ReadInts reads contents from single line file and returns them as []int32.
func ReadLines(filename string) ([]string, error)
ReadLines reads contents from a file and splits them by new lines. A convenience wrapper to ReadLinesOffsetN(filename, 0, -1).
func ReadLinesOffsetN(filename string, offset uint, n int) ([]string, error)
ReadLinesOffsetN reads contents from file and splits them by new line. The offset tells at which line number to start. The count determines the number of lines to read (starting from offset):
n >= 0: at most n lines n < 0: whole file
func Size(v interface{}) int
Size returns how many bytes Write would generate to encode the value v, which must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. If v is neither of these, Size returns -1.
func Sleep(ctx context.Context, interval time.Duration) error
Sleep awaits for provided interval. Can be interrupted by context cancelation.
func StringsContains(target []string, src string) bool
StringsContains checks the src in any string of the target string slice.
func StringsHas(target []string, src string) bool
StringsHas checks the target string slice contains src or not.
func UintToString(orig []uint8) string
func Virtualization() (string, string, error)
func VirtualizationWithContext(ctx context.Context) (string, string, error)
func Write(w io.Writer, order ByteOrder, data interface{}) error
Write writes the binary representation of data into w. Data must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. Bytes written to w are encoded using the specified byte order and read from successive fields of the data. When writing structs, zero values are written for fields with blank (_) field names.
A ByteOrder specifies how to convert byte sequences into 16-, 32-, or 64-bit unsigned integers.
type ByteOrder interface {
Uint16([]byte) uint16
Uint32([]byte) uint32
Uint64([]byte) uint64

PutUint32([]byte, uint32)
PutUint64([]byte, uint64)
