This is the second in a series of articles describing how to get started with using the the JADE Client via its Command Line Interface.

Articles The articles in this series are:

1. Getting Started and Downloading files
2. Simple File Selection
3. More Advanced File Selection

4. File Transfer

5. Checking files for completeness
6. Public / Private Key Authentication

...

In the examples JADE was used to transfer all the files from the directory specified in the source_dir parameter, which is the default setting.

However, the following profile shows how JADE can be used to:

...

In the profile listed below, two new parameters have been added to the sftp_server_2_local_pass example from above: profile presented in the previous article

• file_spec defines the regular expression used to filter file names

• recursive specifies whether the transfer should be carried out recursively (the default value is false)

• With the zero_byte_transfer parameter set to relaxed (i.e. with the file_spec and zero_byte_transfer parameters set as listed above) the test_4.txt zero byte file will not be downloaded.
• A setting of Changing the zero_byte_transfer = no setting to no by commenting in/out the  appropriate line in the profile and rerunning the example will:
  • cause the the test_4.txt file to be ignored as with the relaxed setting and
  • cause an error to be raised if no files with more than zero bytes are found - i.e. if no files are to be transferred.
    This can be demonstrated by activating the alternative file_spec regex (^test_[4]\.txt$) setting which will only match for the zero byte file.
• A setting of zero_byte_transfer = strict will cause an error to be raised if any zero byte files are matched
