Sebb commented on NET-707:
--------------------------
OK, so the ftp server presumably does not support those commands.
I've had a look at the PR, and whilst it may support your test case, I'm not
sure it is sufficiently general. Also it appears to be more complicated than
necessary.
Does OS/400 support filenames which start with one or more spaces?
Can you experiment to see what the output is in such cases?
If there is always a fixed number of spaces after the *STMF column then it will
be easy to change the RE accordingly. If the number varies, then it may be
impossible to detect such cases.
