Constants ¶
const DefaultPathEnv = "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
DefaultPathEnv is unix style list of directories to search for executables. Each directory is separated from the next by a colon ':' character .
Variables ¶
var ( // ErrNotSupportedPlatform means the platform is not supported. ErrNotSupportedPlatform = errors.New("platform and architecture is not supported") )
Functions ¶
func CommandLineToArgv ¶
CommandLineToArgv should not be used on Unix. It simply returns commandLine in the only element in the returned array.
func LUtimesNano ¶
LUtimesNano is used to change access and modification time of the specified path. It's used for symbol link file because syscall.UtimesNano doesn't support a NOFOLLOW flag atm.
func Lgetxattr ¶
Lgetxattr retrieves the value of the extended attribute identified by attr and associated with the given path in the file system. It will returns a nil slice and nil error if the xattr is not set.
func Lsetxattr ¶
Lsetxattr sets the value of the extended attribute identified by attr and associated with the given path in the file system.
func Mkdev ¶
Mkdev is used to build the value of linux devices (in /dev/) which specifies major and minor number of the newly created device special file. Linux device nodes are a bit weird due to backwards compat with 16 bit device nodes. They are, from low to high: the lower 8 bits of the minor, then 12 bits of the major, then the top 12 bits of the minor.
func MkdirAll ¶
MkdirAll creates a directory named path along with any necessary parents, with permission specified by attribute perm for all dir created.
func Mknod ¶
Mknod creates a filesystem node (file, device special file or named pipe) named path with attributes specified by mode and dev.
Types ¶
type MemInfo ¶
type MemInfo struct {
// Total usable RAM (i.e. physical RAM minus a few reserved bits and the
// kernel binary code).
MemTotal int64
// Amount of free memory.
MemFree int64
// Total amount of swap space available.
SwapTotal int64
// Amount of swap space that is currently unused.
SwapFree int64
}
MemInfo contains memory statistics of the host system.
func ReadMemInfo ¶
ReadMemInfo retrieves memory statistics of the host system and returns a MemInfo type.
type StatT ¶
type StatT struct {
// contains filtered or unexported fields
}
StatT type contains status of a file. It contains metadata like permission, owner, group, size, etc about a file.
func Lstat ¶
Lstat takes a path to a file and returns a system.StatT type pertaining to that file.
Throws an error if the file does not exist
func Stat ¶
Stat takes a path to a file and returns a system.StatT type pertaining to that file.
Throws an error if the file does not exist
func (StatT) GetLastModification ¶
GetLastModification returns file's last modification time.
