Functions

func CopyDir

func CopyDir(src, dst string) error

CopyDir recursively copies a source directory to a destination. It does not copy file attributes, but does maintain directory structure. If the destination directory does not exist, CopyDir creates it. If a file with the same name exists at the destination, CopyDir overwrites it.

func CopyFile

func CopyFile(srcPath, dstPath string) error

func DeleteDirContents

func DeleteDirContents(dir string) error

func EnsureClose

func EnsureClose(fileName string, f func() error)

EnsureClose logs a failure when the close does not succeed this should not be used with "just in case closes" and should indeed signal an error

func GetFilesInDir

func GetFilesInDir(dir string) ([]os.DirEntry, error)

GetFilesInDir retrieves a list of directory entries for the given directory. It returns a slice of os.DirEntry representing the files and subdirectories in the directory. An error is returned if there is a problem reading the directory.

func GzipFile

func GzipFile(src, dst string) error

func Shell

func Shell(hook shutdown.CancelHook, writer io.Writer, commandLine string) error

Shell executes a shell command with shell expansion and appends its output to the provided io.Writer.
