createSymlink
:: String -> String -> IO Int
Creates a new symlink. |
removeSymlink
:: String -> IO Int
Deletes a symlink. |
isSymlink
:: String -> IO Bool
Tests whether a file is a symlink. |
linkTarget

quote
:: String -> String

recreateDirectory
:: String -> IO ()

removeDirectoryComplete
:: String -> IO ()
Deletes a directory and its contents, if it exists, otherwise nothing is done. |
safeReadFile
:: String -> IO (Either IOError String)
Reads the complete contents of a file and catches any error (which is returned). |
checkAndGetVisibleDirectoryContents
:: String -> IO [String]
Returns the list of all visible entries in a directory (i.e., not starting with . ) and terminates with an error message if the directory
does not exist.
|
whenFileExists
:: String -> IO () -> IO ()
Performs an action when a file exists. |
ifFileExists
:: String -> IO a -> IO a -> IO a
Performs one of two actions depending on the existence of a file. |
