<br>
Explicitly placing a cd /username/folder command was also attempted.<br>
<br>
Removing -vv and -d are ineffective as well.<br>
<br>
How can lftp be made to avoid automatically issuing the &quot;CWD /&quot;<b=
r>
that causes the unwanted and confusing error message that does<br>
not mean an operation intended by the user actually failed?<br>
<br>
Alternatively, as opposed to stopping the issuance of the &quot;CWD /&quot;=
,<br>
how might one at least suppress its being treated as an error<br>
without also suppressing real errors?<br>
