As such I have a query as I'm a little confused from reading curl's --help
as well as looking at the code:
-Q, --quote CMD Send command(s) to server before transfer (F/SFTP)
-X, --request COMMAND Specify request command to use
-X uses the CURLOPT_CUSTOMREQUEST option, which will be pretty easy for me
to pick up in pop3.c. However, I am lost at -Q and whether I would use
CURLPT_QUOTE, CURLOPT_PREQUOTE or CURLOPT_POSTQUOTE.
-X is used to modify what libcurl would otherwise use.
-Q is used to provide a list of commands to execute at some point, and the
three different QUOTE lists run at different times - like before and after the
"actual" file transfer.
Remember that neither -X nor -Q prevents the actual "main" transfer, -X just
changes it and -Q adds instructions.
Should I be using one or both of these options? My thoughts are to use just
the -X argument so for example curl command lines might be as follows:
--url pop3://mail.domain.com - List all messages
--url pop3://mail.domain.com -X LIST - List all messages
Right, or more likely you'd use -X to do something else than LIST with that
URL as LIST would be the default for that URL. Right?
I would imagine you'd use -Q to do a full series of commands at once while
connected. Like issuing a series of deletes or so.
I have listed all the possible commands above using their POP3 syntax - We
could use full English words such as RETRIEVE, DELETE, RESET etc... ??
No, I think we should pass on exactly what the user specifies as that's what
-X and -Q do for other protocols (well, except for SFTP but SFTP has a binary
protocol so we use the documented names and convert them to binary).
