Hi,
there is no binary/ascii command for sftp. Check with help.

Shalom Roy,

sftp is smarter than ftp. It saves you the trouble of mangling them with ftp by figuring things out for itself. Correctly, nearly 100% of the time.

thanks for the quick responses, i read earlier thread and understand it.
i think some customer needs these commands, because of "ftp" can work these commands.
(for example multiple file transfers like a batch mode)

I believe that when it was designed, the SFTP
did everything in binary. (Because everyone
runs UNIX, it doesn't matter, right?)
Perhaps the protocol has since been extended
to offer a choice, but I don't know. (Check
the RFC?) In any case, it's common for SFTP
clients and servers to know nothing about
different line endings. (Or EBCDIC.)

I gather that some people use programs like
dos2unix and/or unix2dos to compensate for
this oversight. There are also options in
the Info-ZIP Zip and UnZip programs which can
change line endings on text files (Zip: -l,
-ll; UnZip: -a, -aa).

Is there an actual problem which you are
trying to solve, or do you just feel bad
because the "ascii" and "binary" commands are
missing?
