Constants ¶
const ( R perm // read W // write X // execute )
permissions
const PrefixTemp = "tmp-"
PrefixTemp is the prefix to add to temporary files.
Variables ¶
var ( // ErrNotFound indicates when a search does not find a file at 'LookPath()'. ErrNotFound = errors.New("file not found") )
Logger is the global logger. By default, it does not write logs.
Functions ¶
func CheckDir ¶
CheckDir checks if the path exists and if it is a directory.
func CheckFile ¶
CheckFile checks if the path exists and if it is a file.
func CopyFile ¶
CopyFile copies a file from 'src' to 'dst'. If 'src' and 'dst' files exist, and are the same, then return success. Otherwise, copy the file contents from 'src' to 'dst'.
The file will be created if it does not already exist. If the destination file exists, all it's contents will be replaced by the contents of the source file.
func Create ¶
Create creates a new file with b bytes.
func CreateDir ¶
CreateDir creates a directory if it does not exist.
func Dload ¶
Dload downloads a file.
func GroupHas ¶
GroupHas reports whether the named file has all given permissions for the group.
func IsDir ¶
IsDir reports whether if the named file is a directory.
func IsFile ¶
IsFile reports whether the named file is a regular file.
func LookDirExec ¶
LookDirExec looks up the directory of an executable.
func LookPath ¶
LookPath searches for an executable named file in the system directories given one or several executables.
func OthersHave ¶
OthersHave reports whether the named file have all given permissions for the others.
func Overwrite ¶
Overwrite truncates the named file to zero and writes len(b) bytes.
func OwnerHas ¶
OwnerHas reports whether the named file has all given permissions for the owner.
func PathAbsDir ¶
PathAbsDir returns the absolute path of a directory.
func PathRelative ¶
PathRelative returns the relative path of a file.
func TempFile ¶
TempFile creates a temporary file from the source file into the default directory temporary files (see os.TempDir), whose name begins with the prefix. If prefix is the empty string, uses the default value PrefixTemp. Returns the temporary file name.
func Untar ¶
Untar uncompresses a 'tar.gz' or 'tar' file.
Types ¶
type Info ¶
type Info struct {
// contains filtered or unexported fields
}
Info represents a wrapper about os.FileInfo to append some functions.
func NewInfo ¶
NewInfo returns a Info describing the named file.
func (Info) GroupHas ¶
GroupHas reports whether the group has all given permissions.
func (Info) IsDir ¶
IsDir reports whether if it is a directory.
func (Info) IsFile ¶
IsFile reports whether it is a regular file.
func (Info) OthersHave ¶
OthersHave reports whether the others have all given permissions.
func (Info) OwnerHas ¶
OwnerHas reports whether the owner has all given permissions.
