# FileOperation

###

#### final class FileOperation extends Logging

Provides methods for working on files in a stage.

To access an object of this class, use Session.file.

For example:

    // Upload a file to a stage.
    session.file.put("file:///tmp/file1.csv", "@myStage/prefix1")
    // Download a file from a stage.
    session.file.get("@myStage/prefix1/file1.csv", "file:///tmp")

9.  def get(stageLocation: String, targetDirectory: String, options: Map[String, String] = Map()): Array[GetResult]

   Downloads the specified files from a path in a stage (specified by `stageLocation` ) to the local directory specified by `targetLocation` .

   Downloads the specified files from a path in a stage (specified by `stageLocation` ) to the local directory specified by `targetLocation` .

   This method returns the results as an Array of GetResult objects (one for each file). Each object represents the results of downloading a file.

   For example:

       // Upload files to a stage.
       session.file.put("file:///tmp/file_1.csv", "@myStage/prefix2")
       session.file.put("file:///tmp/file_2.csv", "@myStage/prefix2")

       // Download one file from a stage.
       val res1 = session.file.get("@myStage/prefix2/file_1.csv", "file:///tmp/target")
       // Download all the files from @myStage/prefix2.
       val res2 = session.file.get("@myStage/prefix2", "file:///tmp/target2")
       // Download files with names that match a regular expression pattern.
       val getOptions = Map("PATTERN" -> s"'.*file_.*.csv.gz'")
       val res3 = session.file.get("@myStage/prefix2", "file:///tmp/target3", getOptions)

   stageLocation

     The location (a directory or filename on a stage) from which you want to download the files. The `@` prefix is optional.

   targetDirectory

     The path to the local directory where the file(s) should be downloaded. Specify the path in the following format: `file://<path_to_file>/<filename>`. If `targetDirectory` does not already exist, the method creates the directory.

   options

     A Map containing the names and values of optional parameters for the GET command.

   returns

     An Array of PutResult objects (one object for each file downloaded).

27.  def put(localFileName: String, stageLocation: String, options: Map[String, String] = Map()): Array[PutResult]

    Uploads the local files specified by `localFileName` to the stage location specified in `stageLocation` .

    Uploads the local files specified by `localFileName` to the stage location specified in `stageLocation` .

    This method returns the results as an Array of PutResult objects (one for each file). Each object represents the results of uploading a file.

    For example:

        // Upload a file to a stage without compressing the file.
        val putOptions = Map("AUTO_COMPRESS" -> "FALSE")
        val res1 = session.file.put("file:///tmp/file1.csv", "@myStage", putOptions)

        // Upload the CSV files in /tmp with names that start with "file".
        // You can use the wildcard characters "*" and "?" to match multiple files.
        val res2 = session.file.put("file:///tmp/file*.csv", "@myStage/prefix2")

    localFileName

      The path to the local file(s) to upload. Specify the path in the following format: `file://<path_to_file>/<filename>`. (The `file://` prefix is optional.) To match multiple files in the path, you can specify the wildcard characters `*` and `?`.

    stageLocation

      The stage (and prefix) where you want to upload the file(s). The `@` prefix is optional.

    options

      A Map containing the names and values of optional parameters for the PUT command.

    returns

      An Array of PutResult objects (one object for each file uploaded).
