Functions

func CloseFileWithError

func CloseFileWithError(file *os.File, err error) error

func CopyFile

func CopyFile(src, dst string) (err error)

func DirEntriesNameRxVarFirsts

func DirEntriesNameRxVarFirsts(dir string, rx1 *regexp.Regexp) ([]string, error)

DirEntriesNameRxVarFirsts returns a slice of the first regexp match encountered.

func DirEntriesRxSizeGt0

func DirEntriesRxSizeGt0(dir string, fileFilter FileType, rx1 *regexp.Regexp) ([]os.FileInfo, error)

func DirEntriesRxSizeGt0Filepaths

func DirEntriesRxSizeGt0Filepaths(dir string, fileFilter FileType, rx *regexp.Regexp) ([]string, error)

func DirFilesRegexpSubmatchGreatest

func DirFilesRegexpSubmatchGreatest(dir string, rx1 *regexp.Regexp, nonZeroFilesOnly bool) ([]os.FileInfo, error)

DirEntriesRegexpGreatest takes a directory, regular expression and boolean to indicate whether to include zero size files and returns the greatest of a single match in the regular expression.

func DirFilesRegexpSubmatchGreatestSubmatch

func DirFilesRegexpSubmatchGreatestSubmatch(dir string, rx1 *regexp.Regexp, nonZeroFilesOnly bool) (string, error)

DirFilesRegexpSubmatchGreatestSubmatch takes a directory, regular expression and boolean to indicate whether to include zero size files and returns the greatest of a single match in the regular expression.

func DirFromPath

func DirFromPath(path string) (string, error)

func Exists

func Exists(name string) (bool, error)

func FileInfosSplit

func FileInfosSplit(all []os.FileInfo, inclDotDirs bool) ([]os.FileInfo, []os.FileInfo)

func FileinfosNames

func FileinfosNames(fis []os.FileInfo) []string

func FileinfosToFilepaths

func FileinfosToFilepaths(dir string, fileInfos []os.FileInfo) []string

func FilepathModAgeGTE

func FilepathModAgeGTE(path string, s string) (bool, error)

func FilepathModAgeLTE

func FilepathModAgeLTE(path string, s string) (bool, error)

func FilterFilenamesSizeGtZero

func FilterFilenamesSizeGtZero(filepaths ...string) []string

func GetFileModAge

func GetFileModAge(fi os.FileInfo) (time.Duration, error)

func GetFilepathModAge
